He's been here for 5.5 seasons, we've had two different goalkeepers finish in the Team of the Year in that time period, both of them previously journeymen. We currently have a very promising keeper who's settled in nicely after a somewhat unconvincing start. I don't know which other GK coaches we've had who can say they've done that well?
I know Moore and Collins fell out of form having previously played well, but I think they're playing at a level roughly commensurate with their careers to date.
He's apparently responsible for the set pieces too, and we've been among the best teams in the league with those for the past two seasons.
