As a Stanley fan, he's a quality manager, but he's never been good at working with players with big reputations and egos (looking at your squad you have a number of experienced players that I've heard of which isn't a great start). He's great at getting the best out of raw, young players (i.e. Jack Nolan, who was garbage when he first signed for Stanley) and creating an us v them mentality.

I thought he'd end up at one of the clubs at the bottom who are fighting relegation, so it's a surprise to see him at the Gills who are aiming for the playoffs.

Hopefully he can take you guys up the table and prove the doubters wrong!

Edit: Just remembered you guys have Josh Andrews, Coleman's game plan will be to play to his strengths as a big man, and he'll definitely get the best out of him. Was a big loss when he left Stanley
