Okay, I'm going over the day's highlights right now and have stumbled across the mistakes by Ivanovic.
Different positions, of course, but has De Gea ever committed a mistake anywhere close to the universe of Ivanovic today? Maybe the Blackburn mistake, but even then you argue he was in heavy traffic. Ivanovic made TWO bonehead mistakes under no pressure at all. Both led to goals, goals which decided the outcome of the game.
Why does De Gea have to take all the abuse and Ivanovic, who also plays for a big club, does not? Why are there no "news reports" of a transfer to see him off?
