Why is it either/or? Have we not been told by the well informed types that we have a budget (of around £150m net) for Sterling, Pogba and De Bruyne? So if Pogba falls through, no one is going to cost that much and I see no reason we couldn't then split the remaining budget between, say, a £40m central midfielder and £25m left-back. I'd agree De Bruyne (one of my fav players, so I really want him here!) isn't an absolute priority but he should be a signing in addition to other areas we need. If De Bruyne signs, I also think we should sell either Navas or Nasri, probably Navas the best bet, and that would raise more money on top of Dzeko, Jovetic and the others we've already sold.
