Update : Erik ten Hag already has five players who can help mould the future of Manchester United,as date of arrival announced .

 The size of this summer's transfer

 window for Manchester United 

cannot be underestimated.

With the final chapter of a wretched 

2021-22 campaign now very close 

to being rubber-stamped into the history

 books, full focus, for many, has already

 been transferred to next season. The

 arrival of incoming manager Erik ten Hag 

will signal the start of a new chapter

 and, hopefully, happier times 

for United and their army of supporters.

But to ensure happier memories are 

created in the future, the importance 

of the club using this summer's transfer

 window to full effect cannot be highlighted

 enough. United have made too many

 mistakes on the recruitment side of the

 business in recent years and it is hoped

 that Ten Hag, with support from

 Ralf Rangnick, will be able to correct

 those recent errors.

A wealth of positions within the squad

 need to be strengthened this summer, 

not least central-midfield. It has been a 

problematic position for United throughout

 this season and the importance of adding

 fresh blood to that area of the team

 cannot be emphasised enough.

United are weighing up a move for 

Barcelona midfielder Frenkie de Jong, 

whilst they are understood to be working 

on a deal to bring Leeds United midfielder

 Kalvin Phillips to the club. The chances

 of United being able to lure both 

of them to Old Trafford in the same 

window are slim, purely because 

of the sheer size of the transfer fees 

each player would command

Therefore, they're going to have to box

 clever with their recruitment. Fortunately

 for Ten Hag, however, he has a plethora 

of youngsters within the club's youth ranks

 and academy that he could turn to in 

search of quality and potential. He is 

a big believer in developing youth and

 bringing new talent to the fore.

"I do agree that youngsters need to get

 a chance in the first team but they have

 to deserve that chance themselves," 

he once said. "They have to prove that

 they are better than the current players

 or at least have potential to be better."

With that in mind, MEN Sport has taken 

a close look at five players within United's

 ranks who are showing potential and 

could fancy their chances of impressing

 the Dutchman this summer.

Brandon Williams

With both Luke Shaw and Alex Telles 

having struggled to make the left-back spot

 their own over the course of this season

, Brandon Williams will return from his

 loan spell at Norwich City this summer 

feeling optimistic about his chances 

of being involved in Ten Hag's plans 

over pre-season. The 21-year-old has 

shown flashes of his quality for the 

Canaries this season, racking up 

29 appearances in all competitions.

He initially struggled to earn regular 

opportunities under former Norwich 

boss Daniel Farke but he has been a 

much more regular fixture under Dean 

Smith. Although this season will end 

in relegation for the Canaries, the left-

back has made progressive steps 

in his development, benefitting from 

playing regularly in the Premier League.

Williams has already made 50 senior 

appearances for United, too, suggesting

 that he has the potential to play at the

 highest level possible. However, he 

could go up a level or two under Ten 

Hag - a manager renowned for

 developing youth.

Alvaro Fernandez

Like Williams, fellow left-back Alvaro 

Fernandez will fancy his chances of 

knocking on the door of the first-team next

 term, even if it is just to play the role 

of a squad player. He has been a consistent

 performer for the Under-23s this season

, despite only being 19, and is very 

highly rated by those inside Old Trafford.

The jump from Under-23s football to 

the first-team is huge, certainly at a club

 the size of United. However, no shortage

 of players in the past, both at Old Trafford

 and elsewhere, have proven that it is 

not an impossible gap to bridge.

The young Spaniard, who watched the

 Under-18s win the FA Youth Cup on 

Wednesday night, is sound defensively 

and has provided plenty of proof that 

he is capable of fulfilling the duties 

of a modern-day full-back by bombing

 forward. In all competitions this season

, he has scored four goals and claimed

 six assists - a return of ten direct goal

 contributions for a full-back is impressive.

James Garner

The spotlight is likely to shine brighter 

on James Garner than most other United

 youngsters this summer. The central-

midfielder has attracted attention this

 term following a terrific loan spell 

at Nottingham Forest, which could 

still end in promotion to the Premier

 League.

He has excelled on loan at Forest,

 producing a string of outstanding displays

 in the centre of midfield. In a season that

 has seen Forest go from the bottom 

of the table to now, at the halfway stage

 of their play-off semi-final with Sheffield

 United, two games away from the 

Premier League, the 21-year-old has 

played a key role in their success.

As well as proving menacing from set

-pieces, Garner has also dictated matters

 in midfield with his passing ability.

 Furthermore, he will almost certainly 

fancy his chances of becoming a squad

 player next term, especially given 

the fact he did not look out of place 

when Forest faced Arsenal, Leicester 

City and Liverpool in the FA Cup, 

proving that he has the capability 

to play at the highest level.

Hannibal Mejbri

Already a regular with the first-team 

on the training ground, Hannibal Mejbri is 

one of United's most exciting talents, despite

 having only experienced six minutes 

worth of first-team football this season

. In fairness to him, however, he has 

spent a lot of time with the Tunisia squad

, including at the Africa Cup of Nations

 earlier this year, which has meant 

his priorities have lied elsewhere.

But that experience will have helped 

the 19-year-old. He is highly rated by 

those inside Old Trafford and he will

 be hoping to catch Ten Hag's eye in 

pre-season. Considered a creative 

operator, he could provide United 

with an extra element of flair from 

midfield. With Jesse Lingard and 

Juan Mata set to leave the club in the 

summer, Hannibal could be Fernandez

' competition in midfield.

Alejandro Garnacho

United's Youth Cup hero and arguably

 the most exciting player in their 

academy right now, Alejandro Garnachohas

 made significant strides over the last 

few months, suggesting that he could 

be the next breakout star to make a 

name for himself at Old Trafford. Invaluable

 for the Under-18s in ending their 

11-year wait to lift the Youth Cup

, the youngster has notched 15 goals 

and grabbed six assists in all competitions

 this term.
