#5 Mason Mount (Chelsea)
Despite being one of the least known names on this list, Mount is one of the few who has proved himself in the first team of a European club. Having come through the Chelsea youth system, it was no surprise that his first experience of club football came at Vitesse Arnhem. That was a successful spell, as he made 32 Eredivisie appearances last season, scoring an impressive 14 goals from midfield, and providing nine assists.
The real question for Mount is, what’s next? We have seen some good players come through the Chelsea academy in the last few years, as the Blues won consecutive UEFA Youth Leagues in 2015 and 2016, but none of those players have gone on to make their mark in the Chelsea first team, or any first team for that matter. There are a few who have played some Premier League matches, but none who are established players. Mount will probably need a loan move to achieve that, but maybe, Maurizio Sarri might fancy taking a chance on him when he takes over at Stamford Bridge.
