We have proper midfielders. De Zerbi, Juric, Italiano, Gasperini make their midfield play well, with more precise passing and initiative, with worse midfielders. With Locatelli, Fagioli and Rabiot, playing behind Di Maria there is no way to accept that we can't play better in possession. In fact we see it at times during games, usually soon after we concede, that the players play with purpose on the ball.
Keeping possession is also down to the coach. For example, Conte's teams generally don't give the ball away like we do at the moment, and he did it with Parolo, Eder, Giaccherini and De Rossi for the NT.
