Will be essential this year - 4 main competitions and we are in it to win it in all cases. Nobody wants to see an exhausted Tevez or a knackered Silva trudging around the park. Not good for us or the player. And now, finally, we have a squad big enough and talented enough to cope with it all.
This could also be of huge benefit to the younger players and those frozen out before - Ireland and McDermott, Jo even, will possibly find themselves in matches where we need a result and need them to perform,but they'll also be alongside a mixture of key personnel such as Yaya, Barry or NDJ.
My only concern is that Mancini will need to know his best squad & formation for certain games, and god alone knows how he's going to figure that one out.
