City's CEO has confirmed that City won't buy anyone after the CB. Only way would be to sell a high-valued player anyway.
Dzeko on his way of signing a new contract apparently, Milner says he'll wait until he knows how much he'll play, could be months or even next summer then.
Unwanted players that needs to be sold ATM:
Scott Sinclair
Micah Richards
Javi Garcia (to make room for Mangala, non-HG)
Possibly Rodwell (barely gotten minutes in pre-season), but then a new CM would needed. Garcia will probably be the hardest one to sell, average player and ~£70k salary.
