Lineker, Hansen, and Savage did not suggest for a moment that it was a deliberate push by Toure that knocked over Phil Dowd. I know Toure is a clumsy lump but he had his eyes up looking straight ahead where he was going.
Revenge? For what? For ruling that the own goal was legit? He wanted to run straight ahead, ref was in the way. Probably relatively intentional but not revenge or anything like that.
