According to ceefax the Croatians are assigning a defender to Rooney with the specific instruction to get him sent off. If he keeps a cool head then I reackon it's 50/50.. If the Scroats start diving about the place the chances could be alot higher.
Our friend Collina will be watching them like Hawks - he will realise they are up to something and won't stand for it I reckon.
Also it could be a cunning ploy by the Croats to divert our attention and disrupt our concentration. Why else would they actually advertise the fact that they are going to be doing this?
