He's a spiteful, vindictive, petulant man who alienates pretty much everybody who works with him. His siege-mentality act is tired and his histrionics when he's not happy about something are unbecoming for someone in the public eye.
You probably won't want to admit it to yourself (being on a City forum) but whatever he had has now vanished, disappeared. His swagger looks more like a limp nowadays, his bright-eyed, charismatic one-liners and the flirtatious persona he once donned for his post-match interviews have now been replaced by a snarling, wild-eyed polecat.
