Just because he was asked about it doesn't mean he was obliged to dignify what happened with an answer. I've never in my life heard a manager comment on abuse from fans, yet it happens to every single one of them.
Not particularly good, he didn't seem to understand what his instructions were for set pieces (considine had to tell him 4 or 5 times to get into the box for corners) and he was pretty overwhelmed by the pace of the game when he was on the ball and his one attempt at a through ball was thumped at about a hundred miles an hour. He didn't have any real defending to do. Hopefully he'll sort it out though
