We see things very differently then. I think nothing will happen in January, unless someone gets injured.
Getting rid of Berna would be cool, but then you need to replace him. Khedira won't go, he will finally leave in June though.
Eriksen won't happen, Inter would be afraid of doing us any favors here. Besides, I can see him going back to England, only there they can offer him proper wages.
Pogba and Donnarumma won't happen too. The first one is too expensive, the other will renew. Milik will be sold in January IMO, he'll be an opportunity signing for someone but not for us (luck is with us in regards to this one).
Locatelli is almost a must-buy IMO. If Pirlo insists on playing with two holding mids then we need one more player here as McKennie can't really do it IMO, he's not disciplined enough tactically to play that role. Luckily he's much better in a more advanced position as B2B or a (fake) winger in 442 - all action midfielder. For DM we only have Bentancur, Rabiot and Arthur. So adding Locatelli makes a lot of sense.
The rest, I have no idea
