We're certainly going to miss him mate as he offers us something completely different from the rest of the squad, as he showed on Wednesday night.
Personally I hope he takes as long as necessary, longer if need be. Knee ligaments are a very serious injury, if you rush back too soon you can ruin your whole career, look at Falcao.
Kev's long term health is the most important thing, even more important than City winning trophies this year. I hope we cope without out and carry on winning games, but him getting back fully recovered and healthy is the most important thing.
