I wouldn't be surprised if he takes another job in August/September, but the transfer windows must be a nightmare for managers these days. They are probably a nightmare for several at the club but at least for those behind the scenes it's the time when they have to prove their worth to keep their jobs. The managers are probably in need of getting away from it for 5 or 6 weeks but have to keep up with the sagas that develop that infuriate us so much.
For managers like big Sam and Pulis who played and started their management careers in far more straight forward days, it must be a bit testing. Yes they get good money but it must be draining. Allardyce will know that if he sits back and enjoys himself for 4 or 5 months, then it's inevitable that some club will come knocking in Nov/Dec needing rescuing and he can look for another £3m bonus to keep them up. (same would apply to TP).
