It’s hard to say one player but I think there are a few that I am tentatively hopeful for this season:
Return to form:
Rashford - a summer of rest, a more stable environment, has a lot to prove and at his age needs to now consistently perform for the team (as opposed to individually stacking up numbers), month on month, season on season.
Casemiro - hugely experienced, has a reputation for superb conditioning. Brings a profile of player we don’t have in anyone else. Needs to be used properly as a DM, not as a box to box midfielder without adequate team structure. A higher line a should see him return to his best.
Mount - a vastly experienced and underrated player who is still only 25. Has an amazing engine and technical skills to match. Will start with a support role off the bench but has the quality to force himself into the starting xi if he stays injury free.
Onana - has weathered the storm of a difficult first campaign. The only way is up. With Martinez and Shaw fit, and Yoro coming in, has the players in front of him to help his build up game truly shine. Potential link up with Zirkzee is exciting.
Sancho - the big question mark. Is talented but doesn’t have the weapons that many thought he did prior to signing. Can be a tidy and fluid player that can help knit the attack together if he gets his head down and works hard.
Antony - has crumbled under the pressure of the huge fee and off the field distractions. After two years he should have acclimated to life in Manchester and with expectations of his performance at an all time low, can perhaps start to play without the pressure of previous seasons. Has the fundamentals to be a good, if not great player. Fee has to be forgotten. A player who I could see finding his groove in a different position, as he has often looked like a midfielder playing on the wing to me. Has standout qualities in his work rate and resistance to the press.
Development or Breakout seasons:
Amad Diallo - looks a star in the making. This is his season to shine and to make the starting berth his own. He has everything needed to succeed at the highest levels, having significantly added strength and mass to his tiny frame. If he gets the minutes, he has to take his chance. If he does, I think he will be difficult to dislodge from the starting xi.
Garnacho - had a huge breakout season last year and will likely find it harder going this year as opponents learn his game. Will need patience and good coaching to continue his upward trajectory. Is already a weapon with a claim to be in the best xi come first game of the season, but this is a season where he needs to significantly improve his dribbling and finishing. Should be looked at less in terms of statistical goal involvements this season, and more in terms of how well he has developed and refined his game.
Mainoo - a class act through and through. Will need more rotation and support than last season, and for the coaching staff to be patient through potential second season syndrome. Will be at the heart of our midfield for the next 10-15 years if well managed.
Martinez - In many ways the heartbeat of the team because of (a) his passing between the lines, and (b) the power of his personality and presence. Needs to stay injury free for the season and be the defensive leader the team needs.
Hojlund - finally has a player to share the forward rotation with. Feel he is two seasons away from really honing his craft and understanding how to best play the line leading role; nevertheless, expecting to see less of the raw, unrefined product we saw last season, and more of the glimpses of the ruthless finisher and well rounded hold up play we saw in flashes last season. Needs to get in the habit of scoring regularly so it feels like second nature. Feels like with more support, better service, and better management of his minutes, there could be a true “he’s arrived” revelation this campaign.
Dalot - now 25 years old, and has racked up a lot of experience and minutes in the PL. Has all the tools to be a leading PL fullback and will be looking to build on an excellent campaign last season. Really looking for him to emerge this season as a nailed on starter and a top 5 to 10 RB in the world.
I will reserve my commentary on the new signings. I think they’ll need at least a season before any sort of rational analysis can take place. All I can say is that I like their profile, they are of huge potential, but will both require patience.
