I think Mancini and his staff deserve a lot of credit - its no accident that the number of injuries have gone down.
Before the takeover we had to take a few risks on injury-prone players, as the funds available dictated that. People like Mpenza were all we could afford. After the takeover this should no longer have been an issue. Yet Hughes still signed players like Bellamy and Santa Cruz with long histories of injury problems, and for the type of fee where you'd expect a player in peak condition.
When Mancini took over things changed. When Bellamy was shipped out on loan it was a controversial decision. Remember
this outburst by Hughes man Raymond Verheijen? Mancini's methods were supposedly too hard on the players, and the cause of injuries. I wonder what he'd have to say about that now? Mancini took the view that if a player isn't good for two games in a week on a regular basis, he shouldn't be in the team. Maybe his methods did result in some injuries in the short term, but the important part was long term fitness. You can bet he learned a lot about who to ship out from that. No doubt a large part of Jerome Boateng's exit was drinks trolley-gate and the questions that raised, with him perpetually seeming a week from fitness for a good couple of months.
At the same time, the squad has been built with resilience in mind. Its a young squad, Gareth Barry is the oldest player at 31. No nursing veterans through from game to game. You will never get rid of injuries completely, but you can certainly improve your odds. Why else does Mancini like to rotate full-backs? In our favoured formation they do more running at full speed than anyone else in the team, and so are more at risk of injury over the course of the season. Owen Hargreaves is a bit of an outlier in this approach, but then again he was a pay-as-you-play free transfer, with zero risk attached. What you won't see is a fee paid for player with a history of injuries. For every Demba Ba that comes good, there's a Roque Santa Cruz, and we can afford not to take that chance.
