I'd rather there was no cause to let him go, but if it has to happen, so be it. I just don't believe if you're the supposed to be one of the best coaches in the world, you choose not to coach a player within a matter of weeks. It makes far more sense that there's other issues than 'ball at feet'.
As for Barca, I've seen plenty. Theres'a reason why Neuer is the 'sweeper keeper' pinup boy and not Valdes, that's because Valdes was never renowned for it.
This 'ball at his feet' criticism is all since Pep arrived and suddenly everybody's on Hart's back about it. Hart has other issues that we've all seen for many seasons, but the ball at his feet issue isn't one of them (imo) - that's a new buzz phrase being put forward as the reason why Pep doesn't fancy Hart. Nobody was putting that forward as the reason Pellegrini thought he needed some time out.
