Peps seems to like a small squad with lots of versatile players
Centre backs Im happy with, Stones has to be given a chance the club spent 50 million on him. Can't see us spunking more money on yet another central defender.Even Mangala has looked pretty decent in pre season. Then you have Tosin whose signed a new contract (he would be a bit miffed at another centre back signing) and even Denayer.
Full backs again im fine with as Fernandinho can cover right back and Danillo left back. Another signing just seems excessive.
I would love Sanchez but I cant even see how he fits in. We have Sergio, Jesus, Silva, Sterling, Sane, De Bruyne, David Silva plus the likes of Nasri, Roberts, Diaz and Foden who all might play a part next season.
