I almost instantly doze off when reading anything about Pulis, so I'm probably misunderstanding this. He was contractually entitled to this 'survival bonus,' wasn't he? They said 'If you keep us up, we'll give you £2m,' and he duly kept them up.
So while he certainly deserves a massive bollocking for asking for it to be paid earlier than agreed, and seemingly lying about why it was needed earlier than agreed, I don't get why that in itself results in him being told to pay it back. He didn't deceive them to earn the bonus, he deceived them to get it paid a bit earlier than planned.
As I say, reading about Pulis is even worse than watching his teams play, so I guess I've missed something. But it all seems a bit contentious. I mean, clubs often say they've got total faith in a manager, give him a vote of confidence and then sack him a few days later, when it becomes apparent that they've been negotiating with his successor for weeks. That's not 'fraudulent' but it's surely dishonest enough to encourage a high degree of cynicism among managers in how they look after themselves.
