#6 Angel Gomes

He was very impressive at the 2017 U17 World Cup, where he ended up with the winner's medal.
He had made a brief senior team appearance in the 2016/17 season, followed by another one the next season. In the past two seasons, he has played in the U18 Premier League and UEFA Youth League and scored an admirable 17 goals in 14 games.
Angel Gomes joined Manchester United at the age of six and is probably the youngest player on this list. An Attacking midfielder, he's shone on every stage he's played in. Gomes has a certain flair to his game and is often seeing showcasing his tricks to move past defenders. He is a natural number 10, who drifts onto the wide areas to create the play. His creativity, composure and dribbling, along with quick pace, is what sets him aside from the lot.
The way Louis van Gaal had promoted Rashford to the first team after an injury crisis, Gomes can also be expected to be called up to the senior team plans. It's a bit of a long shot for him to be a regular presence this season for the team, but can be expected to be played in a couple of Cup matches for sure. And who knows, he might start a PL game by the end of this season!
