ARSENAL take a slim advantage to the Nou Camp next month thanks to their first ever win over Barcelona.
Arsene Wenger’s men trailed to David Villa’s first-half opener in tonight’s Champions League last-16, first leg clash.
Villa tucked home a perfectly-weighted pass from Lionel Messi in the 27th minute.
Barcelona would have been further ahead had Messi not missed a sitter, while Robin van Persie failed with Arsenal’s best chance going into the interval.
Arsenal made a bright start to the second half with Wilshere just failing to get enough power on his shot to trouble Valdes.
For all their brilliance on the ball, Barcelona were working hard when not in possession, while the Gunners were often guilty of not committing enough players to the attack.
Walcott found space to roam down the left but Sergio Busquets intercepted as Van Persie was about to pounce.
There was greater energy about Arsenal now as they staged a series of attacks, though their cause was not helped when Fabregas sent a free-kick into the arms of Valdes.
Nasri threatened at the near post but Gerard Pique arrived to bundle his cross into touch before Van Persie could connect, while moments later the Dutchman was kept out by Valdes.
Van Persie sent the Emirates wild on 78 minutes when he slammed the ball past Valdez, the keeper guilty of leaving his near post wide open while anticipating a cross from the left.
But better was to follow with a glorious winner from sub Andriy Arshavin after a sweeping counter attack seven minutes from time
