Think its been a long time coming this move. He strikes me as someone who got so lucky that his played for a nation and a club that safeguarded his position despite the mistakes that he has made. Ok Pellegrini did drop him before recalling him for a period of time but it wasn't enough and willy caballero was hardly a brick wall himself.
After getting battered 4-1 by Germany in the 2010 World cup and not even going to Euro 2008 the country was at a low football wise. Carson, Kirkland, Green, Robinson and James were all terrible between them. So in Hart we trusted his youth and built around him. I think to an extent the same things happened at City. No manager has had the "balls" to come in and challenge him as his a well paid, a national number 1 and a fans favorite. Pep has obviously watched him and decided he didn't trust him and shipped him out. Dont think you can blame him. He wasn't great at Torino last season either so his hardly proved Pep wrong. Pep just brought in the wrong replacement in Bravo.
Lets see what Hart does now. Is he driven and determined enough to make West Ham better and reprove himself again? Can he rise to Butland's and Forster's case for number 1? I personally dont think so. Think his more of a Jack Wilshere type and hasn't got the right attitude. If West Ham doesnt work out this season, his career is done.
