Locatelli and Aouar are obvious choices and tick all the boxes but the question is whether Tici will be able to offload some high earners to make room for those two.
In a perfect case scenario you get rid of Ramsey and Rabiot and replace them with the other two. You decrease the wage bill significantly (which will be a goal for the club, I'm sure of it) and you get the better/more reliable players, at least I'm of that opinion.
Zaniolo could be interesting, especially if the club doesn't find the agreement with Dybala. The caveat obviously is the injury record + Roma's willingness to sell, they know he's worth too little after something like this.
Pogba is a joke rumor but it won't go away as long as he's unsettled at MU I guess.
