Its common thing in football now. Look at Arsenal fans with Adebayor last year. Loved giving him stick, but when he shut them up by scoring and celebrating in front of them they couldnt take it.
At Leeds last year I was giving their fans loads of abuse, they scored, they gave me loads of abuse. At the end of the game I walked up the steps and I clapped the few guys I was having banter with. They did the same.
