If Davy Klaasen is ever going to make an impact at Everton it won't be this season.
It has been incredibly difficult for him after quickly being left out by the manager that signed him , not being included by David Unsworth and Sam Allyrdyce making it clear that he wasn't doing enough to be included. He hasn't played since December and coming into a team that is really struggling and to be expected to lift that team given the type of player he is will never happen.
However, he has been extremely professional, I read somewhere that he has impressed the staff at Finch Farm with his attitude. A new manager, a different style and suddenly his face might fit. After the example of Niasse I don't think any player can be written off.
