Whether it was a penalty or not is not the question.
Its when Sir Alex has the balls to believe this team is as ready as he says it is in the press, and whether we become a real attacking team able to apply pressure onto the best, or we are big talking wankers who won't play their best players agaisnt the best.
I've found a new found respect for Arsenal, Wenger gets that team to play their way, no matter the opponent, and their players are confident in their skills and the tactics of their boss in order to execute it.
We deserved nothing, we've played like shit for a month, and its not the player's fault, its Sir Alex's inepitude to believe this side can rip any team to shreds on their day.
He'll learn from this though, watch the United we've seen since August till March over the next 2 weeks.
