This Boga and Loca thingy, gotta say I am a fan. We can, hypothetically, make most of our mercato with trades plus a little cash, we have a lot of players that can be used in some sweet deals.
Starting with Sass, we already have Rogerio at left back that I'm pretty sure is still ours, they can have him permenantly, Sass is a nice team to bet on a youngster, so obviously both Romero and Pellegrini might interest them, along with Hans and that fella we signed from Man City or anyone else we have on our books, lots of options to pick. I'm pretty sure that with Sass we can make a deal that doesn't include money, just trades.
Rugani and Berna won't accept a move to a club like Sassuolo, but Roma and Lazio are something different, both of them can be a bargain chip for Zaniolo or Sergei plus some cash, De Sciglio is another player that wouldn't mind to move to Rome, although I wish he would be ok to return to Milan, him and some cash or another player might get us Theo H if he wants to play in CL and wants to leave.
Danilo is tricky, but we could fool Porto to take him back and try for Jesus Corona, he is a little younger Cuadrado, played a lot at RB this year, played at RW, played a couple of games as a LW, he is a solid tricky speedy player, I like him and he is achievable. They will be champions so it's not impossible to think that even Douglas wouldn't mind to continue there, if Porto likes him.
Kumbulla still hasn't signed for anyone yet, so we could still offer them a player plus cash, if we move all of Pellegrini, Hans, Rogerio etc to Sass for Boga and Locatelli, Romero could be an ok option for Verona.
Would Higuain play for Atalanta, they can't afford his wage, but if we agree terms with Zapata and Gonzalo is ok to play for an ultra attacking team in CL that can also be considered a title rival, if we cover some part of the wage then I think all parties can reach an agreement.
Rabiot will stay, I'm ok with that, Ramsey can be traded, a return to England is an ok option, would he accept Everton in exchange with Kean? I would be ok with that deal.
Release Khedira and gift Matuidi to Lion and take Aouar.
A lot of options, won't spend a lot on a single player but improvement in every area on the field, I am a fan of doing business like that, all of the mentioned players were the first that came to my mind, the mechanism is what I like, player plus cash deal is the way to go this mercato.
Out: Rogerio, Pellegrini, Hans, youngsters, Rugani, Berna, De Sciglio, Danilo, Douglas C, Romero, Higuain, Ramsey, Khedira and Matuidi
In: Boga, Locatelli, Sergej, Theo Hernandez, Jesus Corona, Kumbulla, Zapata, Kean, Aouar.
