Arsenal must keep Kaka quiet - Wenger
"He's the guy who can dominate a situation and in 10 seconds get to the other side of the box and score a goal.
"We need to be more cautious in the centre than we usually are. He's especially dangerous at counter-attacking. I don't know if I'll use Gilberto for him.
"My main worry is to get 11 fit players for the Milan game."
