It’s helped Chelsea and United though, they won’t let anyone rest on there laurels.
It certainly helped Leicester, they were widely criticised for sacking there manager and won the league the next year whilst Watford are in the best position they’ve been for 25 years plus.
As far as I can see Sam isn’t even a proper appointment by the board. They wanted him until the summer, he wouldn’t sign so after trying every other avenue they panicked and gave him the minimum he’d accept.
I think the plan has always been to sack him in May, the contract is the amount they’re happy to pay him to go.
