He left cause Milner and Barry were sold without his blessing, and he got none of the money to replace them!!
he left cause of the chairman and chief ex. selling our best players and not wanting to replace them at least ? petrov should be captain player manager, he to be a good role modal loool
He left because the owner sensibly refused to allow him to carry on with spending ridiculous money for ****e players. He had a tantrum and stormed out basically.
