I'm hoping that the injured players like Aguero, Zabaleta and Kompany are back playing by then.
I really doubt City will buy to cover short term injuries. Unless City change our style of play, I don't think there's room to buy another striker. If we buy a forward, and Aguero is fit, then they are on the bench.
Long term I'd like to see City play a front 3 where the wide players can score. Players like Neymar, Sanchez etc Suarez. But players like that are very difficult to sign. Maybe Mahrez? At the moment we have one central striker - Aguero - and if he's out no one seems capable of coming in. However Kelechi does look very promising.
