It's a bit clear that he's our future number 9 from Ole and the club's stance around him. This summer is going to be very interesting. Pogba fixing a puzzle on the left has really thrown a spanner in the works. Ole even mentioned that United have to keep him away from defending as much, essentially stating that he's no longer viewed as a midfielder. We probably won't sell him as a result ( he'll get a new contract) and will be a key part of our attack moving forward. This pushes Rashford to competing for the spot on the right or as a centre forward. Greenwood may very well be going head to head with Marcus. This also essentially reduces the likelihood that we spend money on a right winger, with Cavani also potentially staying and Amad featuring more in the team.
My best guess is that Amad will eventually compete head to head with Rashford for the spot on the right, Martial will be sold, Mason will transition to our number 9 rather quickly starting by rotating with Cavani before completely taking over. We won't sign an attacker this window. If we do, it will most likely be a striker that can compete with Mason rather than dominate moving forward ( tbh there aren't many world class strikers) similar to the Benzema/ Higuain or Drogba/Gudjohnsen dynamic.
Pogba moving left does mean we have the opportunity to season a more capable all around midfielder this summer; that can help us build out of the back, whilst being capable defensively, finally allowing our attackers to attack. Personally, I would replace both roles as I don't feel either Mctominay or Fred are United starter quality, particularly in the modern game. However, I would suggest only signing one player ( Kessie, Paredes, Camavinga, Narhaus even Tielmens) and assess the other options we have partnering them. How would Fred look next to a player who takes the build up responsibility? Can Mctominay improve at all and stop hiding? Can Garner translate his play from the championship to the premier league like Grealish did? Can Mejbri stand out and take over that spot? Fred is good enough to hold down the spot in the worst case scenario for at least one season.
Defensively, signing a more aerially inclined defender than Lindelof should be the mission. Maguire is a fantastic centre back that takes on too much responsibility imo. He's not Van Dijk, so he can't cover 2 roles consistently, but he's been doing a good job most of the time in that regard. We can win the league without signing a defender, its our midfield that has prevented us from challenging previously. However, if we want to ensure that we match the best possible team City can provide, signing a better defender than Lindelof would help with that. We haven't lost a game by more than 2 goals in the league since Spurs beat us 6-1 to start ( our early campaign woes were down to fitness). Since then we have only lost 1 game, despite rarely putting up dominant performances. Part of that is down to our defence, if we improve on that, thereby dropping the goals conceded from set pieces, corners, aerial mishaps, we would have the best defence in the league.
