It looks all done and dusted from the Camp Nou now, as just three minutes after Xavi's goal that knotted up the tie on aggregate, Lionel Messi has scored a penalty for FC Barcelona to put them 4-3 ahead on aggregate in their UEFA Champions League Round of 16 tie against Arsenal FC. It seemed like it would only be a matter of time before Barca took control of the game after Robin Van Persie saw a second yellow card for time wasting, but the speed with which they've put Arsenal to the sword is still a bit stunning, despite the fact that it was all Barca even when the teams were playing 11 vs. 11.
Pedro was the man who drew the penalty, as he was hacked down in the box by Laurent Koscielny. It was a stone cold penalty if there ever was one, but there was still a significant delay in the referee pointing to the penalty spot. The Barcelona players began to protest before the penalty was eventually given. Lionel Messi stepped up to the spot and converted, scoring his 45th goal of the season in all competitions and expanding his Barcelona club record for goals in the UEFA Champions League.
With 10 men and a deficit at the Camp Nou, this tie seems all but over for Arsenal.
