I too am getting sick of Ronaldo's off-the-ball antics. But he has cut downn on diving. He is just too fast and the slightest touch against him, when he's at full throttle, can easily knock him or anyone down.
I seriously wonder if those who call him a diver have ever played football at full speed, as a winger or a striker. Ahem. Ahem. Seriously, it's so easy to fall at the slightest touch, even, as you go full-steam ahead.
As bro Dime has mentioned, he's going to win the the FIFA World Player of the Year 2008 award. So give the man something more than mere negatives.
There are worse and more recalcitrant divers around.
