Damien, if you are reading this, please take the following into consideration.
Who will be our midfield conductor? Who can boss a game and run the show? I desperately want to see a 3 man midfield implemented. The midfield is the most important part of the squad in the modern game. If we can establish a good midfield, the rest will follow.
Di Gregorio is fine as a starter, with Perin as a backup. Upgrading the goalkeeper position is just premature optimisation at this point.
In defence, Bremer is one of the best defenders in world football and hopefully he's fully recovered from inury. Kalulu established himself as one of the best defenders in Serie A. Gatti shouldn't be a starter, but he is an ok squad player. At fullback, I want to see what Cabal and Alberto Costa are fully capable of. Give both consistent playing time. Keep Cambiaso unless an offer for €60 million+ arrives. Let Savona get more experience.
In midfield, don't touch Khephren Thuram. Make decision/s on Koopmeiners and Douglas Luiz. If we aren't selling, then they need to be starting games. It is absolutely ridiculous to have these guys on high salaries sitting on the bench. If they aren't part of the project then sell ASAP and identify replacements. We can't build a midfield around McKennie and Locatelli.
Forwards, don't touch Kenan Yildiz. Pay the option for Chico Conceicao (it's good business). Negotiate another loan for Kolo Muani. Sort out the mess with Susan. Signing an elite striker is worthless if he doesn't receive service.
