He has left the club through mutual consent. That must've cost a bit of money to sort out, but at least clears the way for someone to come in in January.
A sad one this as I remember a talented player from his previous clubs. Even though he is only 24 clearly something is amiss with him and we are not in a position to wait around until he regains his fitness and confidence.
It appears that Sarcevic wasn't happy hear and actively sought to leave the club. There has been no pay off made to him, sounds like it was an honest and decent move by him.
