There is zero need to get hostile or try 'push' him out or need any leverage over him. If he chooses to see his contract out, whether it is for a bonus next year, one last trophy hurrah, lack of options or whatever, then the club will be comfortable with that as they were when they offered it, and he has certainly earned the right too. He will leave if he is tempted elsewhere, not because the club would want him out.
Plenty of benefits for us too, him seeing his contract out, if that's what happens.
