Welcome to Eurosport's live coverage of the Cop del Rey quarter-final first leg between Real Madrid and Barcelona at the Camp Nou!

The final whistle goes, and it's another Barca win at the Bernabeu! Real's game plan was working until Puyol scored his header, and the unlikely goal hero Abidal has given Barca the advantage for next week's second leg.

The referee plays advantage after a late challenge by Carvalho on Adriano. The move ends ina wild shot wide. Carvalho perhaps fortunate not to see another yellow card and then a red.

Three minutes of added time to be played.

Barcelona substitution: Isaac Cuenca replaces Fabregas.

There are a few Real fans who are starting to file out of the stadium. They must be sick of the sight of Barca. Carvalho is booked for a desperate trip on Messi.

Barcelona substitution: Thiago Alcantara replaces Xavi.

Fabregas has just picked up a lighter or something similar and handed it tot he referee.

Nice sweeping move forward from Real, but Ronaldo's eventual effort is blocked before it can get through and test Pinto.

Barcelona substitution: Adriano replaces Sanchez.

In 10 matches at the Bernabeu, Lionel Messi has only once failed to score or assist a goal.

Real substitution: Esteban Granero replaces Pepe.

Puyol taks himself into the referee's book as he protests a decision.

That is Abidal's second ever goal for Barca in four-and-a-half years at the club!

GOAL!! REAL MADRID 1-2 BARCELONA!! Messi dinks a little ball into the box and Abidal beats the offside trap. The France defender takes the ball on his chest and hits a low finish past Casillas!

Second-half possession: Real 29%-71% Barca.

Even Manchester United and England striker Wayne Rooney is upset about Pepe's cheeky tread on Messi's hand. He just tweeted: "Pepe. What an idiot. Sometimes people wind u up."

Casillas is off his line to claim a cross with authority. He tries for the quick counter but the ball is soon back in Barca's possession. The visitors are really beginning to hog the ball now.

Iniesta plays intot he path of Messi int he box but it's a good interception from Coentrao. The Portuguese left-back has not got forward nearly as much as he usually does this evening.

Xavi delivers a fabulous free-kick from the left flank and Busquets glances it over the bar! That should have been on target!

Pepe has to get involved, doesn't he? With Messi sat on the floor, the Poruguese steps on his hand! Luckily for him, the officials didn't see that.
