Well you can't complain about sending all the youngsters on loan and then also complain when they get to play and they make mistakes.
I think he has done pretty well, given it is his first time of playing against top class opposition. He switched off for a second and Inzaghi has scored. Inzaghi has done exactly that heaps of time through the years and to defenders who are much better and more experienced than Criscito. The main thing is he learns from it.
He is good now and, with time and the right guidance, can become top class. If we play him he will improve faster.
