He's just shouting for sake of it (talking nonesense) should be sacked, out of his depth and not good enough - essentially. Bring in one of Villas boas/Deschamps/Van Gaaal
He didn't achieve the goal set out for him (see: top 4 finish) playing his archaic system and basically writing the book on how not to manage a football team. Since execution is not an option, the next best option would be to fire him.
