#10. Jack Grealish – 21 years old
Jack Grealish is considered by many to be one of the best young English players at the moment. He is excellent in possession, has good technique with two feet, and an ability to burst past players. Traits like this have helped make him a coveted player. Unfortunately for England and Aston Villa fans, Grealish can’t seem to settle himself off the pitch. A now-famous picture of a drunk Jack Grealish passed out on the floor emerged on social media last year which has earned him a reputation. That was furthered when the recent training ground spat with one of Villa’s coaching staff left Grealish with a club suspension. Let’s hope for Villa’s sake that Grealish heeds this warning and starts fulfilling his potential.
