Not read the thread, but of course he should be played if Warne thinks he is the right selection.

He's a bloke who's job is playing football. He is currently employed by Rotherham, but like any employee can do, he's given the matter some thought and wants to play somewhere else.

I doubt if it's 'personal' for him and it shouldn't be for anyone else. If his decision is based upon some sort of issue with the club, Warne or his teammates then that is something that should be taken into account when the decision is made as to whether to include him in the team. Otherwise if he wants to go, it's in his and the club's interest to play and put himself in the shop window.
