Ole Gunnar Solskjaer could clear some of the old players from United's squad, but he could also finally decide that some controversial players are worth staying as reserve candidates.
Manchester United fans have always loved Anthony Martial, but to be fair, after a disappointing performance last season, more and more people will lose patience with him.
So could Anthony Martial leave Manchester United?
The Frenchman played alongside Marcus Rashford and Mason Greenwood at the end of the 2019-20 season, but he couldn't maintain that consistency as he left the following season.
According to the analysis of the photo, it must be time to sell him, otherwise the Red Devils may find it difficult to find so many buyers in the near future.
A simple question – Phil Jones has now completely lost love for United and it's time to leave.
Even if Solskjaer doesn't plan to bring in a new centre-back this summer, Jones is sure to be a selling option as long as someone is willing to accept him.
Van de Beek had a tough first season at Manchester United, where he did well at Ajax but he barely left the bench at Old Trafford.
The Netherlands international may be tempted to leave to make sure he can play properly, but we think it would be a mistake to let him go before he is given a chance.
We think Van der Beek should be a reserve player – but now it's time to give him more playing time!
Andrea Pereira has been loaned out several times and it's hard to imagine how many at United want to keep him any longer.
Obviously there's a good player out there, but that hasn't happened to Daniel James yet.
The young Welshman's move from Swansea City's Championship to one of the biggest clubs in the summer of 2019 may have been a bit too fast for him.
We think there is a reason to have James on loan to another Premier League club for the coming season, as it will give him a better chance to play in the regular season and gain confidence at that level.
Once looked like a good young player, but Tuanzebe may not have a future at United.
Like Jones, it's hard to see Axeltuan Zebe as an urgent option in Ole Gunnar Solskjaer's backline, so we think they'll be selling the 23-year-old soon.
It was a tricky decision for Ole Gunnar Solskjaer, as Jesse Lingard was loaned to West Ham in the second half of last season.
Few would have thought that Jesse Lingard would be so impressive, but now there may be a real need to give him a chance to play in the first team at Manchester United.
Still, with Sancho joining, it's a very clear signal that Jesse Lingard will find it more difficult to get into Solskjaer's camp, so we expect that in this case they will be more likely to decide to sell.
As a decent young player, Brandon Williams is clearly not ready to be United's starter and he will definitely need to leave United for a while to gain experience in the Premier League.
It looks like Williams could be loaned out rather than permanently sacked and if he wants to have a long-term future at Old Trafford, he has to take the opportunity to impress.
After being loaned to AC Milan last season, Diogo Dalot returned to Manchester United this summer, and it's a bit surprising that he hasn't left yet.
While Aaron Wan-Bissaka is not the world's most attacking full-back, Dalot still has a place in Solskjaer's squad.
We may have guessed wrong, but if United's other transfers don't work out, we can imagine they'll choose to keep Darot.
