RVP shot the ball more or less knowing he is offside (not heard the call part, but shooting at frustration kinda thing), seen him do it before, act petulant, and players getting yellow for it, usually for first yellow, quite petty to give 2nd yellow for that, but acting like he did all game, not suprised that eventually happend. The penalty was clear, bit of a joke to say otherwise.
I REALLY dont get what Wenger was thinking, Arsenal neither played defensively or offensively enough to try to impact the game in any way in that direction. No urgency forward when needed, nor any defensive teamwork to shut down shut, they were in some weird middleground, where their defense was high as usual giving away chances in rapid rate (goalies and Djourou saving the day alot). Was laughable kept losing possession in seconds. Yeah Barca at home is toughest as it can get, but you either bunker down with discpline, or try to play your own offensive game, no half assed middleground that ensures you get owned even more. Pathetic.
