It was a great stroke of luck," Denis Cerlini, the youth coach who trained Diallo at Boca Barco, told BBC Sport."From the very first moment, it was evident the kid was special. He was very bold and quick, possessed great technique and a strong shot, and executed everything at great speed."Amad was popular in the dressing room. He made a lot of friends, learned Italian and seemed to be a very determined guy who knew exactly what he wanted."After a season with Boca Barco, Diallo sealed a move to Atalanta in 2015.Compared to Lionel Messi by Atalanta playersDiallo began training with Atalanta’s senior squad at the age of 16 and, according to the club’s captain Papu Gomez, was an absolute handful.“There are defenders in the first team that sometimes cannot stop him,” Gomez was quoted saying by United’s official website. “To stop him in training, we have to kick him! He plays like Messi.”High praise indeed.p1es0inb4kcgo1aghl3efdvdrvf.jpgThe giants he previously had trials withBefore joining Atalanta, Diallo had trials with Juventus, AC Milan and Inter.The three Italian giants might end up kicking themselves for not signing the starlet.He recently ditched ’Traore’ from his nameOriginally known as ‘Amad Diallo Traore’, the youngster confirmed on Instagram in October that he was ditching ’Traore’.“I updated with the new name,” he wrote on his Instagram story.His personalityMan Utd fans should have no worries about Diallo’s personality.“Coaches who have worked with him closely and journalists who have followed his development talk about a winger of phenomenal attacking potential, a player who is disciplined, dedicated and extremely determined to reach the top,” writes BBC Sport’s Michael Yokhin.p1es0iskot1d2g5c6n69clq1fnjj.jpgHe enjoyed a dream professional debutDiallo made his profession debut in 2019, entering the fray as a 79th-minute substitute for Atalanta against Udinese.

I’m looking forward to starting."

What impressed United’s scouts?

United claim their scouts had been aware of Diallo’s talent for a number of years.

“They were so impressed with Diallo’s skill, pace and mentality,” the Red Devils’ website says, “securing his services became an objective.”

Fears over his physicality

Diallo was first spotted by Giovanni Galli, the former Fiorentina, AC Milan and Napoli goalkeeper who played for Italy at the 1986 World Cup.

The 62-year-old is obviously a huge fan of the youngster but fears he may need to bulk up in order to flourish in the Premier League.

"He must add a few kilograms of weight in order to survive in the Premier League," Galli told BBC Sport.

However, one top scout at an unnamed club - per ESPN - claims the teenager is able to handle himself on the pitch.

"Physical profile: can seem lightweight, but deals well with contact. Able to stay on his feet even when facing strong challenges. Low point of gravity, good balance,” the report reads. “Impressive change of direction with and without the ball. Impressive body control and coordination. Very quick on short spaces, loses some power and speed over longer distances. More continuous than most players of his age, impact persists throughout the game."

His style of play

The same scout report provides in-depth details about Diallo’s playing style.

Initially a central midfielder, the report says: "Characteristic inverted winger who likes to cut in on his left foot from the right. Prefers to take up positions relatively deep in order to participate in build-up rather than go directly for a goal or the conclusive phase, but is also effective closer to the goal and penalty area. Less effective on the left, but can roam with success in central positions."

He’s already tormented Man City

Diallo stole the show against Manchester City in the UEFA Youth League back in October 2019, scoring one goal and setting up another in a 3-1 victory for Atalanta.

Diallo has shone on his Champions League debut

United fans were left buzzing in December 2020 after watching Diallo’s eye-catching highlights from his Champions League debut against FC Midtjylland.

He was only on the pitch for 22 minutes, but he still managed to make a big impression on Europe’s biggest stage…

Which shirt number will he wear at Man Utd?

Diallo takes the No. 19 shirt, previously worn by Marcus Rashford, Danny Welbeck, Gerard Pique, Edwin van der Sar and Dwight Yorke among others.

“Hope it brings you lots of luck bro,” Rashford said to the United new boy on Instagram.

His two role models at Old Trafford

Diallo has already been in contact with compatriot Eric Bailly in recent months. He admits that he’ll also seek advice from Paul Pogba.

“Eric will be a definite reference point for me," Diallo said. "I’ve actually already been in touch with him over the last few months and we’ve been chatting.

"I’ll be asking him for advice and will be listening to all he says, and also the other players who speak French and Italian like [Paul] Pogba for example, he will be another good reference point for me.”

Named by UEFA’s latest ’50 for the future’ list

Diallo’s name has been included alongside the likes of Jude Bellingham, Curtis Jones and Daniel Maldini on UEFA’s ‘ones to watch for 2021’ list.

Will he emerge to be the pick of the bunch? Only time will tell, but Solskjaer and Man Utd’s fans will feel quietly optimistic.
