#8 Will Hughes (Watford)
Will Hughes is another player who has been around for a while, but there's a general feeling that he's yet to fulfill his big potential.
Hughes has been very highly rated ever since making his debut for England U21 as a 17-year-old. However, he had to wait for his chance in the Premier League for many years after being stuck at Derby County.
2019-20 will be the third Premier League season for Hughes at Watford, and big things are expected after he became a regular first-teamer last season. He featured 32 times in the league, with 31 of the games coming as a starter.
After struggling with injuries throughout his young career, 2018-19 was the first season in a while that Hughes didn't have a single problem with his health - which helped him become one of the key players for the Hornets. However, there should still be more to come considering Hughes was involved in just six league goals (two goals scored, four goals assisted) last season.
