Barcelona v Arsenal - in pictures

Worried, Arsene? After last year's trip to Camp Nou when his side were humbled 4-1, the Frenchman must be feeling a degree of trepidation. Lionel Messi was in devilish form that night scoring a hat-trick to eclipse Nicklas Bendtner's early strike. The difference tonight, of course, is that Arsenal have arrived in Catalonia clutching a 2-1 first leg advantage (last year it was 2-2) so the onus will be on Barca ...

His replacement, Manuel Almunia, is helpless in stoppage time at the end of the first half when Messi nicks the ball over his head and volleys Barcelona into the lead. The decisive through-ball was played by Xavi, but it was Fabregas's careless back-heel which gave the hosts possession on the edge of the box Photograph: Carl Recine/Action Images

Still, Arsenal only need a goal to swing the tie back in their favour. In the closing stages Bendtner is given a glorious opportunity by Jack Wilshere who slides a teasing cross in his direction with the outside of his boot ... but the Dane's first touch is poor and the chance is stifled Photograph: Shaun Botterill/Getty Images

It ends 3-1 on the night and 4-3 on aggregate, knocking Arsenal out of Europe. Nasri and Koscielny vent their anger at the referee before Wenger gives him an earful as they head to the dressing rooms.
