There was an incident when he first rocked up on these shores when a ball boy was slow in returning the ball, and for a fleeting second it looked like Bingo was going to thump the kid. I knew then I was looking into the eyes a man with serious mental health issues. He has done nothing since then to alter my views, on the contrary.
I also think his OTT exuberance and his disproportionate celebrations are calculated and worked out in advance. He knows full well he's playing to the house, appeasing the dipper fans whilst simultaneously provoking the opposition fans.
So yes, I think he has mental issues. Serious mental issues.
