21.38 Germany 8 Spain 1. An absolutely ludicrous pair of results, but tonight's was no less deserved than Bayern's yesterday. Dortmund were better organised, fantastically energetic, and utterly lethal in front of goal. The scoreline leaves a Real comeback at home within the realms of possibility, but Dortmund's reponse to a gifted equaliser should give them heart. On this form, Lewandowski will score at least twice at the Bernabéu. Thanks for your company, I'll talk to you again soon.

90+3 min Real have a corner. Chance to change the complexion drastically. It drops for Varane who spins, shoots, and just misses the top corner. Ooh, that was inches!

89 min Big save from Weidenfeller! Comes charging off his line to throw himself at Ronaldo's feet when a goal looked likely.

87 min Ronaldo is found in space on the right and brings it down beautifully, but there's Hummels with an excellent challenge to deny him space to shoot.

84 min Not often that a game is so decided that you can't take a brief break from liveblogging to investigate a news report... German paper Bild is reporting that Madrid coach Jose Mourinho's return to Chelsea is "all but agreed". Make of that what you will, just for my sake, pray that it's all over quickly. No-one likes a saga.

83 min Now it's Grosskreutz on for Piszczek for the Germans. Say what you like about Dortmund, they've got an awful lot of players with the letter sequence "zcz" in their names.

82 min Dortmund have a free kick wide on the right. They really should be playing low-tempo keep-ball now, but if anything they're hungry for more goals. Blaszczykowski coming off, Kehl replaces him. Footballing history has, quite literally, been re-written over the past couple of nights:

Twitter: OptaJoe - 4 - This is the first time in Champions League history that two teams have conceded 4+ goals in one game in a set of semi-finals. Gubbed.

79 min Poor old (young) Varane, he can't get close to Lewandowski. The Pole wants five, takes aim for the top corner and unleashes a fierecely curling shot. Bashed away with unnecessary panache, by Lopez.

77 min Real attacking, but Borussia growing with confidence with every attack succesfully repelled. Thoughts turning now to the return legs. Are they both going to be rubbish? There's surely some life left in one of those ties.

71 min Ozil and Alonso combine to improve the latter's crossing angle after the free kick. Dortmund clear without much bother. Di Maria's on for Modric for the visitors.

70 min Lewandowski is booked for being too good. It's actually for an industrial-strength block on Ramos. No need for that, Real have a free kick 40ish yards away. Here's Peter Littley in answer to the question posed above:

This goes back a very long way and your question has brought it all back to me. For me it was the sale of goal keeper Malcolm Finlayson from Millwall to Wolves back in 1956 , I think that was the year. His transfer hurt the most because he was the very first player to sign my autograph book. I was 6 or 7 at the time and Malcolm was the tallest man I had ever seen. When he left it was like losing a friend. I still have that book. I believe he is still around, certainly hope so.

69 min Benzema on for the wholly ineffective Higuain. Ronaldo is played in behind the Dortmund defence, but is offside.

67 min GOAL!! Dortmund 4 Real Madrid 1 (Lewandowski) Bang. What a night for Robert Lewandowski. Hit high and hard down the middle, no chance for the diving Lopez. Que pasa, Espana?

64 min Ozil is booked before taking a free kick but showing an imaginary card to the ref. What has the world come to? The free kick is hung towards Varane at the far post, Dortmund clear behind for a corner.

62 min Gundogan does tremendously to beat Khedira and Varane with a barnstorming run, before shooting with Lewandowskiesque power. Lopez turns it over the bar excellently. Real just about clear the corner. Here's an excellent stat from that Twitter:

Twitter: Armen Bedakian - Lewandowski is the first player to score a hat-trick against Real Madrid in Champions League history.

61 min Real, seemingly asleep for the first 15 minutes of this half, have roused themselves a little. Ronaldo is fed inside the box on the left-hand side. He fools Piszczek with a silly cutback, but his cross is well cleared by Subotic.

60 min Here's Lewandowski celebrating his second goal, with Lopez folornly appealing for offside in the background:

58 min Modric has a go from Old Trafford range, but this one's not troubling Weidenfeller. Slow and low and straightforward.

55 min GOAL!! Dortmund 3 Real Madrid 1 (Lewandowski) That is outstanding stuff from Robert Lewandowski for his hat-trick. Schmelzer's pass deflects to the big Pole close to the far post. Lovely touch to take it away from Pepe and Alonso, rolling the ball with the sole of his foot with total calm. Then a glorious, emphatic finish high into the net at Lopez's near post.

54 min Khedira booked... Or is it Modric? Referee's card-pointing direction saying one thing, on screen graphic saying another. I'll be honest, I've seen better-presented televised football matches.

52 min A replay, at last. Lewandowski was onside, and did well to be alert as Reus stabbed it forward. Lewandowski turned Pepe beautifully to make space for a straightforward finish. Madrid, to a man, had stopped and were appealing. Silly boys.

50 min GOAL!! Dortmund 2 Real Madrid 1 (Lewandowski) Lewandowksi, looking fairly clearly offside from a Reus pass, finishes past a shocked Lopez for his second of the game. I'd love to tell you some more, but the goal rather caught me by surprise, and the German-provided TV coverage is yet to provide us with a replay.

49 min Dortmund still going at this with pace, but it's more about doing things quickly to put Real under pressure, rather than trying to cleanly string together potent attacking moves. It's worked for them this time, a couple of fast throws result in a dubious corner, which Lopez catches with ease.

20.31 It wasn't looking like a classic, but we do, at least, have some proper drama now. Dortmund were so consumed with their penalty appeal that they forgot they had to defend for a little while. Mounting Real pressure resulted in an equaliser, but it was gifted to Ronaldo by a dreadful mistake from Hummels. See you in 15.

45 min Some fairly bizarre officiating from Dutch referee Björn Kuipers, who ignores what looks to be a clear foul on Reus wide on the left. Dortmund wobbling, but Subotic makes a key block as Modric crosses from the right.

43 min GOAL!! Dortmund 1 Real Madrid 1 (Ronaldo) Oh, tragedy for Mats Hummels. Dortmund are seething after Reus is denied a penalty under pressure from Varane moments earlier. Reus went down a little too easily for me. Moments later a throw comes to Hummels awkwardly. He's under pressure from Higuain and gigantically undercooks a backpass to Weidenfeller. Higuain siezes on the rotten pass, Ronaldo's up with him, and duly teed up for a tap-in.

42 min Ozil with a perfectly-weighted ball out to Ronaldo on the left. He crosses, seemingly over-hitting it, but finds Modric on the end of it. He heads towards Higuaian, who lays it back to Alonso. He shoots, at approx one million miles per hour. It's blocked.

41 min Coentrao capitalises on some uneasy defending from Schmelzer, but can't provide the early cross which might have teed up one of three team-mates in the box.

39 min Gotze nearly profits from an early throw as Ramos has a little nap at right back. Just out of his reach, and behind for a goal kick.

35 min Schmelzer and Reus get themselves in a bit of a muddle on the left. Dortmund back into this now as an attacking force, but some of their lightning fast interplay is a little off. Here's Cristiano Ronaldo attempting to reach the Dortmund crossbar via Wiedenfeller:

32 min Real enjoying the majority of the ball now. Dortmund looking less keen to press them as manically as they did at the beginning of the game, but there's Blaszczykowski charging in as Real cross the halfway line. He's past Coentrao with a gorgeous turn and races into the exposed space on Real's left. Higuain tracks him all the way and eventually makes an excellent tackle in the box as Blaszczykowski shapes to shoot. Hits the Pole and is behind for a goal kick.

29 min Another Real free kick wide on the left, this one is won, fortunately, by Coentrao. Another penetrating cross by Alonso, but Weidenfeller does well again, punching clear with authority.

26 min Real's building up a head of set piece-based steam. Alonso swings in a dangerous looking ball from the left, but Dortmund clear, then break. Promisingly, until Bender hurries a ball towards Blaszczykowski on the right. Coentrao is well positioned to intercept.

24 min Ronaldo opens his legs to their normal 80s hair-metal singer width ahead of striking a free kick from 30 yars. He beats the wall, and forces Weidenfeller to beat it clear. Good save.

22 min The game has become a little flat now. Madrid seeing more of the ball, but can't find their passing range yet. Alonso tries a trademark ping to the wing for Ronaldo, but it's overhit and out for a throw. Here's Robert Lewandowski's opening goal:

18 min Hard to view this game as anything other than the sequel to last night. The Barcelona-over Germany-brilliant narrative has been so prevalent today that this feels like more of the same. But Madrid seem to have stabilised here, and Dortmund are over-reliant on hopeful balls up to Lewandowski. Can't see another 4-0. You know it's a massive European night when Soren Assman has sent you an email:

Evenin', Thom! Say, did you know that lately, Dortmund has been trying to outrout Munich, and failed? They only win by five or six goals, at max, in the league this year. Munich managed to win by seven once. But Dortmund always tries their best. Also, the reason the Götze transfer was published yesterday? To stop Dortmund in the semifinals. Cause Munich would HATE losing the final to them, ANYBODY but them. Would ruin their entire season. I hear rumors that Dortmund will opt for Christian Eriksen as Götze replacement. You can imagine my delight - the prospect alone makes me grin like a pink pony! What's with Spanish defense these days? Used to be better, or is that only my impression?

16 min Gundogan, ever-so impressive so far, is caught in the face by an over-exuberant Khedira. Dortmund comfortably winning the scrap in the middle. This fan will be delighted:

14 min First time we've really seen Ronaldo on the ball. He gallops inside from the left and finds Ozil in the middle, who looks to have been fouled by Reus, but it's not given.

11 min So far, so last night. Germans flying, Spaniards can't get going. The visitors have got no answers for the pressing and running of Dortmund.

8 min GOAL!! Dortmund 1 Real Madrid 0 (Lewandowski) Real being over-run in the middle, and all over the pitch. Gundogan wins it in the middle again and finds Gotze hugging the left touchline. He beats Ramos with ease and delivers a beautiful, preacitcally undefendable cross. Lewandowski easily gets ahead of Varane and finishes unerringly while stretching.

7 min Great run by Reus! He takes on Varane after Bender dispossesses Khedira in the middle and eventually cuts past the centre back and gets himself into shooting range. He must have travelled 30 yards, and forces a smart save by Lopez, Lewandowski close to getting on the end of it.

6 min Not an enthralling start, but encouraging signs that we're going to have en entertaining tussle in the middle of the pitch, with Gundogan, Khedira, Bender and Alonso all unafraid to get their foot in and have a scrap.

3 min Dortmund not looking particularly interested in doing things quickly when they're on the ball, but their pressing on Real when it's given away is very intense, Coentrao being hurried into a hoof as he's closed down at speed by Blaszczykowski.

Twitter: OptaJoe - 1 - Real Madrid have won only one of their seven Champions League semi-final away fixtures & that was in Spain (vs Barca 2002). Timid.

Borussia Dortmund: Weidenfeller; Piszczek, Subotic, Hummels, Schmelzer; Bender, Gundogan; Gotze, Reus, Błaszczykowski; LewandowskiSubs: Langerak, Felipe Santana, Leitner, Sahin, Grosskreutz, Schieber.

Real Madrid: Diego Lopez; Ramos, Varane, Pepe, Coentrao; Alonso, Khedira; Modric, Ozil, Ronaldo; Higuain.Subs: Casillas, Albiol, Nacho, Kaka, Callejón, Di Maria, Benzema.

Yes, Jose lied to us. Modric in for Di Maria, who, to be fair, was only "hopefully" in the pre-announced line-up, but does make the bench.

After last night's torch-passing ceremony in Munich we are back in Germany for another Champions League semi that, like last night, is tremendously exciting in prospect.

The intriguing thing about this game, very much the b-side to last night's, is that Dortmund and Real have been able to concentrate exclusively on this competition for some time now, such is the dominance of Barcelona and Bayern in their respective domestic competitions.

That could be to their advantage, with both sides able to play well-rested and meticulously-prepared team. It could also hinder both, because we all know that it's difficult to turn on the tap marked "win games with ease" if that's not been the recent habit.

In the last round both sides were involved in mesmerising games, against Malaga and Galatasaray respectively. That both made such entertaining meals of getting past ostensibly second-tier Champions League teams suggests that there are defensive and mental frailties that need to be addressed.

It could mean we're in for another evening of high drama and questionable defending, which would suit me just fine.

The build-up has been dominated by one man, Mario Gotze, who is soon to be somebody that Borussia fans used to know by joining Bayern Munich this summer. The reception he receives tonight will be interesting, as will Dortmund's response to the sale of one of their best players to a team 20 points ahead of them in the Bundesliga.

I normally promise team news at this point. Jose Mourinho scooped me, by announcing his yesterday. Straight from la boca del caballo:

We will play with Diego Lopez, Sergio Ramos, Pepe, Raphael Varane, Fabio Coentrao, Sami Khedira, Xabi Alonso, Mesut Ozil, Gonzalo Higuain, Cristiano Ronaldo and hopefully Angel Di Maria.
