Following Carrick's appointment as head coach, the Manchester United youth setup is set for a major overhaul. The Daily Mail reports that a new crop of promising youngsters will step up to the senior squad, whereas those who are certain to be sidelined or seek more first-team action will depart Old Trafford during the summer transfer window.

According to reports, Shea Lacey, Jack and Tyler Fletcher, Gabriel, Jayden Kamason, Jacob Devaney, and Jim Swietz are seven promising prospects who could get opportunities under Carrick. Most of them have already featured for the first team in the two pre-season friendlies against Wrexham and Rosenborg.
Lacey scored a goal as a number 10, earning Carrick's approval, and will stay at the club at least until the first half of next season. After January, a decision will be made on whether he continues with Manchester United or goes out on loan. The Fletcher brothers are the sons of U18 head coach Darren Fletcher, so they naturally receive extra chances. Taylor even captained the team in the second half of the first match and has been named in Scotland's squad for this summer's World Cup.
The 15-year-old Gabriel traveled with the team for the match against Rosenborg, although he did not make his debut. He has long been regarded as the next "crown prince" of the academy and has the potential to break the club's record for the youngest ever appearance.
The aforementioned four players are designated by Manchester United as the top priority talents. Midfielder Jacob Devaney scored a goal, while right-back Kamason provided two assists, and they may also receive support.
In contrast, goalkeeper Radek Vitek, left-back Harry Amass, and midfielders Dan Gore and Toby Collyer have been informed that they are unlikely to get regular playing time next season and are available for sale or loan. The club prioritizes developing a select few designated players, and most other U21 players can be considered for loan or even outright sale.

These players are expected to generate around £20 million in transfer fees for Manchester United, with the most valuable likely being 22-year-old Czech goalkeeper Radek Vitek. Vitek impressed on loan at Championship side Bristol City last season, not only as a regular starter but also sweeping all the club's end-of-season player awards, including teammates' Player of the Year, Young Player of the Year, and Fans' Player of the Year.
Vitek is fully capable of establishing himself in Manchester United's first team, but he is unwilling to be a backup to Senna Lammers and wants to be a starter. Therefore, he can only be transferred or loaned again. With only two years left on his contract, unless he agrees to an extension, United hopes to sell him permanently for around £15 million.
Left-back Harry Amass, 19, was also loaned to the Championship last season. In the first half, he performed very well for the relegation-threatened Sheffield Wednesday, winning the club's monthly player award consecutively. United recalled him in January and loaned him to Norwich City, but that didn't go well as Amass suffered a serious injury after just one game and was ruled out for the season.
Amass, nicknamed "the new Luke Shaw," performed well in pre-season, so fans are quite unhappy with the decision to sell him. However, from a personal perspective, if the Red Devils sign a new left-back, he would have little chance of staying in the team, so a transfer to another club would indeed be better for his development. The Athletic reports that Manchester United has set a price tag of £6 million for him.
Dan Gore and Collyer have been loaned out multiple times, plagued by injuries, and they are no longer young. Gore is about to turn 22, and Collyer is already 22. Staying at Manchester United would certainly be unpromising. However, both have only one year left on their contracts, so it is unlikely they will fetch a high price.

On Transfermarkt, Collyer is valued at €5 million, while Gore is worth only €1 million. The Red Devils are likely to sell them at a bargain price, including a sell-on clause, hoping that they will perform well in the future and generate additional income for the club upon their next transfer.
