He would do it to make himself attractive to other clubs. If he wants to play then these are the things a player of his subpar quality will need to do.

Right, but you are aware that a club would be in touch long before through an agent etc so he'd be aware if there was interest. The club would then ask him to terminate etc if they couldn't agree a deal or knew they wouldn't be able to with Everton.
If you had a job where you knew there was no progression, then you wouldn't leave unless you had another job lined up, would you?
