Soccer:Barcelona were deserving of their 3-2 Spanish Super Cup first leg victory at the Nou Camp. They may though rue not taking full advantage after dominating for large spells against a Real Madrid side who failed to find the cohesion that had seen them go unbeaten in three of their last four trips to the Catalan stadium.

The home side 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 Lionel Messi 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 were struggling to manage any prolonged possession and were relieved to see referee Carlos Clos Gomez wave away appeals for a penalty when Alexis Sanchez tumbled in the box under pressure from Sergio Ramos.

However, for all their 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 visitors who took the lead 10 minutes into the second period as Memit Ozil’s corner was headed 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 put Pedro in behind Fabio Coentrao and the Spanish 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 (local) kick-off time, and the visitors’ luck 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. Barcelona led 3-1 at this point.

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 Victor Valdes’ error allowed Angel Di Maria to give Madrid a lifeline heading into the return at the Bernabeu next Wednesday.
