"I've been in the dressing room and the first thing I asked was that I hoped there was no racist element involved and they, the players, said there wasn't. The Aston Villa coaching staff said there wasn't too," he told Sky Sports immediately after the game at Villa Park on Monday night.
"I'm really surprised at Dion. I've never seen him do anything like that in his career and I suspect he may wake up in the morning and I think he's been silly.
"Towards the end there was some serious provocation going on and some of the things going on were getting out of hand and silly. But I'm delighted with the discipline of my players. I didn't see any rash challenges from them.
"To come here and do the double on them is a great achievement. We wanted to pick up something and we're delighted that we're six points ahead of Bolton."
