First of all; I certainly hope Miloš Krasić won't get suspended because the chance of beating Bilan at the weekend wouldn't be so big, though he does deserve a suspension and I'm sure he'll get one for the dive. I've watched Miloš Krasić since he first broke through at Vojvodina, all the way at CSKA Moscow as well and he had a similar dive against Tom' Tomsk earlier this season. Check at the 1:07-mark, not the best angle but I watched the whole game and it was very similar to the one yesterday against Bologna.
Just to add, he's always been diving. That's what I hate about his game as it can get a bit embarassing.
