Barcelona vs Real Madrid

Cristiano Ronaldo headed Real into the lead against the run of play 10 minutes into the second half from Mesut Ozil's corner, but Barcelona responded as Pedro showed great poise to slot home a minute later.

The action then raced from end to end and it was the host which forged ahead 20 minutes from time when Lionel Messi scored from the penalty spot after Sergio Ramos had brought down Andres Iniesta.

Then a terrific jinking run from Iniesta freed Xavi to stroke home Barcelona's third goal seven minutes later.

However, the visitor was gifted a way back into the tie five minutes from time when Barcelona goalkeeper Victor Valdes tried to dribble around Angel Di Maria and only succeeded in gifting the Argentinian an open goal.

Barcelona was deserving of the victory but may rue not taking full advantage after dominating for large spells against a Real side which failed to find the cohesion that had seen it go unbeaten in three of its last four trips to the Nou Camp.

Messi had the first real chance of the game when a typically sharp Barcelona passing exchange freed Dani Alves down the right and his cut-back found the Argentinian on the edge of the penalty area, but his left-footed drive flew just off target.

The world player of the year then had an even better opportunity from similar range as he skipped past Alvaro Arbeloa but this time pulled his shot wide of the other upright.

Real was struggling to manage any prolonged possession and was relieved to see referee Carlos Clos Gomez wave away appeals for a penalty when Alexis Sanchez tumbled in the box under pressure from Ramos.

However, for all its dominance Barcelona only had another two long-range efforts on goal as Pedro's drive was tipped over by Iker Casillas before Xavi shot just over from similar range.

And it was the visitor which took the lead 10 minutes into the second period as Ozil's corner was bulleted in by Ronaldo for his fourth goal in his last four away games against Barcelona.

The lead lasted less than a minute as a wonderful ball over the top from Javier Mascherano found Pedro in behind Fabio Coentrao and the Spain international slotted past Casillas.

The game then became increasingly stretched as both sides tired slightly from playing in the still searing heat, despite the 10.30pm kick-off time, and the visitor's luck with Gomez eventually ran out as Iniesta was brought down inside the area by Ramos and Messi stepped up to thunder home the penalty.

Moments later Iniesta showed incredible speed of foot to dance past three Real challenges and slip a pass through for Xavi to sidefoot past Casillas.

Messi then had a great chance to all but seal the trophy but he was denied from point-blank range by Casillas, and within seconds the complexion of the tie had completely changed as Valdes' error allowed Di Maria to give Madrid a lifeline heading into the return at the Bernabeu next week.
