I'd sell Rabiot, Bentancur and Ramsey with no hesitation if we got decent offers. Ramsey is what he is, he's a good and useful player who is often injured, and we knew that when we signed him to his big contract.
Sign a Locatelli and a Aouar level / type of player and have some faith in Fagioli and Ranocchia to come through and fight for places. I know people would rather sign a third player for big money but the economic situation is difficult, especially if Dybala goes for nothing. We have two good CM prospects now which we didn't have when we signed Rabiot.
