It's funny.
Guy almost certainly takes abuse every match, from one set of fans or both, from the coaching staff and players, makes one comment in a video and that's it.
It's insane really. He's going to have an opinion, he's going to have a bias, you just hope he's professional enough in his job to not let it effect his decision making.
He's a doughnut for allowing himself to be filmed saying it by anyone.
