Would depend on the reasons for him resigning.
If he was promised new training facilities, a transfer budget and a poodle, and all Wally could come up with was 3 stolen traffic cones and a calendar from Battersea, then he could say he was forced to resign and his career was being damaged, especially as he turned down a more lucrative opportunity to stay.
Could just be that he woke up one morning and thought... 'sod this for a game of soilders, I'm off'.
Two different reasons for resignation, one unlikely to see compensation paid, the other might be a more negotiated position.
Either way, why would a fan know the terms?
