I wonder if he used the same argument to Hecky if he was rightly giving them what-for at half time. "You can't say that to me when we've won 8 out of the last 10 games". There's nothing wrong with the fans giving them a kick up the backside either. As soon as I read it, I thought of Rooney at the 2010 World Cup.
So it's ok for certain fans to kick off at the players but woe betide they give it back? Non-issue. Move on.
You're right. A team plays poorly, goes into half time a goal down and a few boos ring out. There's nothing for ANYONE to get their knickers in a twist about. A routine Saturday afternoon at many grounds I would have thought.
