I don't agree with the not having the heart theory because I've watched him, as a small player getting lumps kicked out of him for 5 years show more heart than the majority of players in the team. He's worked hard for the team since the day he got here and this last four months is the only time he's looked genuinely off the pace - which comes after another injury.Spot on Cleavers. Whether because of injury or because he genuinely doesn't have the heart, Silva has been defensively weak for along time and has gotten away with it whilst the forum boo-boys paint Toure as the devil incarnate. The number of times David has left full backs exposed, let midfield runners jog away from him, stood with his hands on his hips because he hasn't gotten a call,these are things that Pep will not put up with - and I agree it isn't exclusive to Silva. ALL our attacking players with the exception of Sterling and Navas struggle to do the defensive side of their jobs with any diligence or any real commitment over 90 minutes. Maybe Pellegrini allows them that kind of freedom and expects his defenders to deal with one on ones - but Pep won't have it.
I think Pep will be chomping at the bit at the thought of working with somebody with Silvas ability. If he's after him working harder and changing his game I'm as equally sure that Silva is up for the challenge.
