Chelsea boss Roberto di Matteo insists Oscar is not a diver.

Di Matteo denied Oscar had dived during their win over Stoke City and insisted ref Mike Oliver was wrong to book him.

He said: "There was contact. Maybe the referee didn't feel there was enough contact.

"He shouldn't have booked him from my point of view.

"After the game, he can watch a replay and it's easy to make that decision."
