For me its Rice first and foremost. Get him in early in the window and then see what other business is out there. I really came around on a potential Rice/Caicedo midfield after this January window but feel like Caicedo might become a bidding war we don't want.
The Milinkovic-Savic rumors are interesting to me. He's a tough player to get a feel for - reminds me of Pogba in that he's more of a luxury midfielder. He won't dominate a game on his own but if you have a great team around him, he could be that extra piece to take the team to the next level, especially in the Xhaka role. Sounds like he would be available for a decent fee this summer too.
After that, I'd want to just be opportunistic in the market for another winger/attacker. If a Diaby/Leao were to become available, see if we can pounce. We don't need a lot of players in but the players we bring in this summer have to be world class IMO, with the exception of trying to get Fresneda before he hits another level.
