While you can't really argue that Cole's tackle was reckless and therefore a red card, no doubt we'll see that sort of tackle end up with nothing more than a yellow more often than not.
As for the game as a whole, we actually looked the better side while we were down to 10 men and really should have got the 2nd goal in the first 20mins of the 2nd half. While I never expected to come about as it did (I actually done a Pigeon after the Rosicky save too), you always expected Arsenal would score the longer the game went on.
Taking the positives from the game; N'gog looks better and held his own (especially after the red card) and good to see how the team played even when we went down to 10 men.
