One window is enough, but it needs to be brutal. I think on top of Sané and Silva, Otamendi, Cancelo, Stones, Gundogan & Marez need to go. Zinchenko if there's a good offer.
Then we need a LB, 2CB, back up RB, a deep midfielder and 2 forwards.
We have the money to do it, we're already 65m up after Sané and Leeds compulsory purchase of Jack Harrison.
My big question is if Pep is cut-throat enough to not just chuck away the obvious ones like Otamendi, but if he will realise Gundogan and Mahrez are never going to be good enough at the highest level for this team to replicate or surpass the success he had at Barca.
