He just had a poor game, it happens, especially with young players. He found it hard to get into the game as everything went through Grey, who played very well.
I'm sure Frank, Coady and the squad know how to handle it, and I think being subbed was the right thing.
If we could hold off on the pitchfork and dunking instincts for a bit, and see it for what it was, a bad game, that would be nice.
