Lassana Diarra isn't particularly amused with some decisions made by Wolfgang Stark today, having been penalised several times already for tackles that he considers perfectly legal. He has a point, too, but it doesn't matter - the fouls in the midfield are giving Barcelona a great starting point from which to mount forays into the Real Madrid half, and they're taking full advantage, taking the game to their hosts and starting to worry the defence.
Their latest attack sees Xavi draw Madrid right back Alvaro Arbeloa inside, allowing the midfielder to flick wide to Pedro advancing down the left wing. Unfortunately for Barcelona, a decent cross was not forthcoming, and the chance was well cleared by the massed ranks of white shirts packing the penalty area. Barcelona are probably fairly happy with the way things have gone so far - right now they're in total control of the match.
