Warnock's two-fingered gesture to the Kop

The Sheffield United boss was seen to put two fingers up at the Kop after Michael Owen had scored Liverpool's second goal, as they sang "Warnock, Warnock, what's the score?"

What was possibly intended as a joke was not seen that way by some fans, who have made a complaint to the FA.

With claims that Warnock also made racist remarks about Stephane Henchoz at the end of the game, it is possible that the Blades boss could be in serious trouble.
