He came in, looked around and thought what the fuck is going on here. As soon as he got here he made it clear that he would be using the squad properly and building a team. Using subs just to change things if he thinks it's not working or if someone has had a bit of a knock. Keeping the squad match fit in case someone does have to come in for a spell. He plays players to their strengths and the better he knows them the better they are playing and the more belief they have.
Add that into the fact that they are actually feeling pressure this year, have a manager they hate but are stuck with unless they pay a lot of cash out then we have a recipe for sharks.
