It was a mistake for the third goal - though a shared one with a few other players (he had no easy out pass) and, given the positional change and fatigue of playing with 10 men, there's enough rope to cut him some slack.
I think it's inevitable that younger players are going to be slightly inconsistent. Also, we know he wouldn't have been playing if other players had been fit, and by and large, he's been one of the big pluses for us this year. So I'm pretty surprised at the impatience and lack of support for him.
