He will lose his job because he wasn't strong enough to stand up to the egos in the dressing room. The second a player stops working hard, you drop them. You don't continue to let them rip the pee out of you, phoning in performance like they're a 47 year old Robbie Williams at Soccer Aid after a pint and a kebab, purely out of fear of the PR reprisals.
And it isn't one player, but it sets the tone for squad. He's been big enough to make examples of players due to off field issues but seldom for on field performances.
Like reality TV stars who get guaranteed book deals when they come out of 'the house' or leave 'the island' regardless of what actual literary talent they have, if you can not give a toss on the pitch and be 99.99% sure of the fact you're never, ever losing your place in the starting line up, then why would you improve? Your attitude stinks to begin with so self pride isn't presenting itself any time soon.
He's allowed that to permeate throughout the squad and that's entirely on him. Shame as I think he could have succeeded were he to have the balls to. I cannot remember the time a poor individual display in a match was responded to by someone losing their place.
Injuries? Off field issue? Sure. But so many players have been so dreadful for so long the fact you rarely ever see players lose their place because of their consistently poor form from whistle to whistle, is a massive issue with his management for me.
