Amazing stuff! Malaga's players have collapsed, Dortmund's celebrate like they have won the Champions League. They were down and out, and now they are in the semi finals. Is their name on the cup? Thanks for looking in!
Reus' cross, Schieber mishit the ball, but Santana tapped home from on the line- might have been offside. What a finish!
The ball is pumped up towards Lewandowski, but its too far ahead and Willy collects. Dortmunbd running out of time and ideas.
Joaquin rampages down the right, but gets closed down just inisde the Dortmund area and the chance is gone.
Isco set up Baptista, he rolled it across the box and Eliseu tapped it in, although he looked offside on replay. Malaga are almost there - what a shock!
Brilliant save from Willy! Reus should have scored, he slid in eight yards out but the Malaga keeper threw himself across to deflect the ball behind.
Toulalan tries another long range shot, but it lacks the direction of his earlier thunderbolt and only threatens Row Z.
Duda should get a corner but does not, and gets replaced after complaining to the referee, by Eliseu.
Close! Toulalan's low shot from 30 yards is hit fiercely straight at Weidenfeller, who punches the ball away
Blaszczykowski caught offside as Malaga move up when the ball is chipped over from the right. Lewandowski nods the ball in, but the flag was already up.
Dortmund get a free kick this time, Reus sends iot over from the left but its a Malaga shirt that gets there first.
It's more end to end than earlier, Malaga are coming back at Dortmund, who are obviously having to go for it.
Theres trouble as Schmelzer tangles with Gamez, but it is the Malaga player who is booked. Looked like a half-punch from the Dortmund player - bizarre.
Daniel Diangangu: "It will be a tough game both sides will go for it which will leave Malaga exposed it will end 3-1 Dortmund"
Santana's long pass finds Gotze in the box, but his volley is not controlled, skewing a long way off to the left. But that was a good chance for Dortmund.
Isco dances down to the bye line down the right, and his decent low cross is cut out by a home boot inside the area.
Great save from Weidenfeller, Joaquin nipped in at a free kick for a header and the home keeper palmed it away to his left.
Half time, and it is 1-1. Malaga going through as it stands, but plenty more to come in this match I think. Let me know what you think - @TimOscroft or firstname.lastname@example.org.
Joaquin wastes a great chance! The free kick was floated over, but Joaquin's header from near the penalty spot lacked venom, and Weidenfeller saved - needed a lot more "oomph".
A Malaga goal kick is won back by Dortmund easily, bur Demichellis is wily enough to stop the attack in its tracks.
Gotze passed sideways at pace to Reus, but his deft touch changed the direction of the attack, wrongfooting the Malaga defence. Brilliant.
Wonderful flick with his heel from Reus gave Lewandowski nthe chance, he raced into the area and flicked the ball over the advancing Malaga keeper. Sublime goal.
Lewandowski just about gets to head a cross goalwards, and although Willy drops the ball he recovers to reclaim it.
Joaquin cuts in from the left but his chip over to the other flank is cut out, but Dortmund look a bit shakey at the back.
Blaszczykowski knocks the ball too long for a goal kick - not happening for the hosts at the moment.
Somewhat against the run of play, but Joaquin took his chance expertly. Julio Baptista was also involved.
Isco knocked the ball down to Joaquin on the edge of the box, and he rolled it in with his left foot, just inside the post past Weidenfeller's left hand. Great finish!
Julio Baptista tries to be clever surrounded by four defenders, but does not have the skill to wriggle free on the touch line by the Dortmund box.
Malaga are really struggling to get and then keep the ball, very little from them since the opening five minutes.
Blaszczykowski badly overhits a pass to Piszczek, the Malaga defence were stretched but have a let-off.
Down the middle is Dortmund's modus operandi at the moment, with Lewandowski showing why some top clubs are looking at him.
Lewandowski tries to catch out Willy from outside the box with the Malaga keeper on the six-yard line, but the ball floats over the bar.
A cute backheel from Reus to Blaszczykowski on the left flank catches the eye, but the Germans are offside to relieve the pressure.
Reus was closing in to a Piszczek cross but Gamez cut it out on the corner of the box at the last moment.
Home side looking very confident at the moment, biding their time on the ball. No sense of worry from the crowd either.
Bender fouls Joaquin, who rolled around several times after the slight contact, and the Dortmund player is booked.
Lewandowski called just offside to end a move where Dormund sliced straight through the Malaga defence.
Decent move sees Piszczek coming in off the right flank, but the ball deflects and loops into Willy's arms.
Gotze coming very deep for the ball for Dortmund, but Malaga are getting the ball back a lot at the moment.
Malaga on the front foot although it is quite cagey - they will be content to hit on the break, and an away goal would do wonders.
Isco tries to control a high ball over his shoulder but can't, and it goes out for a throw near the Dortmund area.
Tonight's ref is Scotland's Craig Thomson, who watches as the two sides give the ball back to eachother in the first minute before Antunes fires high and wide.
Jack Bullions: "As much as I want Malaga to defeat all the odds... 3-0 Dortmund" Let me know what you think @TimOscroft or email@example.com.
A mere 65,000 in the ground tonight due to restrictions on standing, but that's still not too bad is it? The teams are about to emerge into a typical cacophony.
Malaga have only conceded six goals in the Champions League so far this season - their first in this competition. And when at Villarreal, Pellegrini piloted them to the semi-finals, also in the club's debut season in Europe's elite club competition.
But what about the players that will start tonight? Isco has also been linked with moves abroad, while Blaszczykowski, Gotze, and Lewandowski have their admirers all over Europe.
Alex Bullions on Twitter says: "Malaga are the underdogs for this match but I have no doubt that they will produce a win and travel to the next round."
JB gets in touch on Twitter to correctly say that Roque Santa Cruz's last game for Man City was 13th November 2010, 0-0 against Birmingham City. The Paraguayan only lost once to Dortmund in 11 meetings while at Bayern Munich, BTW. And having interviewed him once or twice, I can tell you he's a nice fella too.
Both tonight's coaches have been linked with moves to the Premier League - what do you think? Would you like to see Jurgen Klopp or Manuel Pellegrini managing your club? Get in touch @TimOscroft on Twitter, or email firstname.lastname@example.org.
Timal Mihiranga Subasingha Kottawatta: "BVB one of front runner for the title this season for me. We saw 1st leg last week. Like always BVB played well & they create many chances. But their finish wasn't good. But I'm sure they will win easily today. My scoreline will be 3-0. Lewandowski, Gotze & Reus."
And speaking of the current Premier League champions, there is a City player on the teamsheet - technically. Roque Santa Cruz is on the Malaga bench - it's nearly four years since he joined City, but I'll give you a mention if you let me know when his last City game was and who against.
Can Dortmund win through and maybe even go all the way to regain the crown of European champions? Or can Malaga spring a surprise? Get in touch @TimOscroft, or on email@example.com.
As for Dortmund, they are on home soil in one of the best club grounds in Europe, whjere the legacy of that 1997 Champions League triumph lives on. They have looked good all season in this competition and have been many people's dark horses - including mine, after seeing how good they were at times against Man City & Real Madrid.
Malaga's preparations may have been affected by manager Manuel Pellegrini flying to Chile to attend his father's funeral. He will be at the Westfalenstadion tonight after returning today, and the talk among the Malaga squad has been of winning tonight for Pellegrini.
Chris Green predicts a 4-1 win for the German side, while Wasim Shah says it will be a bit narrower but also sees Dortmund making the semi's - 2-1.
Three changes for Malaga, with Duda, Camacho and Sergio Sanchez in for Weligton, Saviola and Iturra.
Borussia Dortmund: Weidenfeller, Piszczek, Subotic, Felipe Santana, Schmelzer, Gundogan, Bender, Blaszczykowski, Gotze, Reus, Lewandowski. Subs: Langerak, Kehl, Leitner, Hummels, Sahin, Grosskreutz, Schieber.
Malaga: Willy, Jesus Gamez, Demichelis, Sergio Sanchez, Antunes, Joaquin, Toulalan, Camacho, Duda, Isco, Julio Baptista. Subs: Kameni, Lugano, Saviola, Piazon, Eliseu, Santa Cruz, Francisco Portillo.
It is 0-0 as we prepare for the second leg, how do you see tonight's game going? Get in touch with your thoughts and predictions at firstname.lastname@example.org, or if Twitter is your thing then tweet me @TimOscroft.
