His positioning is ridiculous. Man is wide shaping to cross a ball and Krul 'is still' covering his near post....Hence it takes him a lifetime to scuttle over and no chance to stop the header. Krul was actually in the back of the net.
This. I urge anyone to watch his positioning for WBA's goal the other week. His starting position was so wrong it boggled the mind. I was screaming at him before the kick came in that his left side was where it'll end up, and it ended up exactly there. Again, putting the blame solely on the players is wrong. There is clearly a coaching issue compounding these errors. He may be thick, but he isn't as useless as some here make out. He has massive potential, but for that potential to bloom, he needs to get his finger out AND has to be trained by someone who knows what they're doing.
The other thing is that he hasn't worked on his 'bambi legs'...The brain sends the message and then he sort of skitters and stumbles to where he is meant to be 60 light years later. Look at De Gea and how he's firmed up his body and looks so much stronger than when he first arrived. And he's blind as well...But has quickly become better than Krul when they had basically the same potential.
