Aston Villa boss Martin O'Neill has accused Chelsea midfielder Michael Ballack of diving to get Zat Knight sent-off during yesterday's 4-4 draw.

"Zat Knight's sending off was a major moment," said O'Neill. "I've seen it a couple of times now and while I'm aware that I have the benefit of replays I will look at it again. I might appeal and we have until noon to do so. It wasn't a penalty. The Chelsea player went over and there was no contact."
