It's hard to say since we don't know who the manager will be.
Also if Pogba leaves as expected, the midfield should probably be Fred + 2 new signings with McTominay as the first man filling in, and we don't even really know the front 3 though if we don't buy big it'll likely be Rashford-Martial-James with Greenwood getting a lot of playing time.
So, if we buy a pure 10 then we need someone to play alongside Fred behind him, whereas if we buy a box to box player we might play 4-3-3, hard to say. Could even be a new manager who wants to play 4-4-2 to get Rashford up top with Martial/Greenwood and let James play his best position of left wing, in which case we'd need someone who can start on the right and a #8 or holding mid to start with Fred or McTominay and Bruno wouldn't fit at all.
