I thought Krasic did better yesterday than he has recently.
However, it wasn't that he was beating his man, it's just that he actually passed the ball most of the time instead of trying and failing to run with it.
You can't play top level football for well over a year without any proper rest without suffering some sort of fatigue.
It is possible that it is mental fatigue, rather a physical issue, though.
Part of the reason I haven't really praised Matri much is that he only scored one goal, when he had two great chances and one half chance.
