Nothing wrong with Vermaelen bombing forward when we needed a goal against Newcastle or even against Fulham, it was late in the game and we needed some drive injected into the forward line.
But there was no reason for him to get forward against Norwich in the first half, we talk about patient and possession football but that's completely undermined if your defender is tearing forward from the back with 60 minutes of the game remaining.
Also, in the past Vermaelen used to join the midfield while carrying the ball from the back. That's fine, because he has the ball and he was in control of the situation. Now days he's running forward hoping the ball gets to him, somehow. It's moronic.
