There are many great young talents in world football today, and especially in the Premier League, but who are the very best starlets in England's top division?
Here is a team of the best players of 21 and under in each position.
Goalkeeper | Thibaut Courtois | Chelsea
Although he has never actually played a game in the Premier League, if Mourinho decides to keep him this season we could see him get game time and eventually take over Petr Cech in net. The 21-year-old has already proved his talent with some great performances on loan for Atletico Madrid last season.
Right-back | Carl Jenkinson | Arsenal
Jenkinson had a good season last year and has proved on numerous occasions that he is more than capable to replace Bacary Sagna and also push for the competitive England right-back slot with the likes of Kyle Walker, Glen Johnson and Micah Richards.
Centre-back | Matija Nastasic | Man City
He was one of Manchester City's better players last season, playing consistently well all season - unlike many of his City team-mates. He possesses great composure considering his tender age of just 20-years-old. He also kept England international Joleon Lescott out of the team all season.
Centre-back | Steven Caulker | Tottenham
After a good loan spell at Swansea Caulker came back to Spurs and had an excellent season for them last year. He played 28 games and was solid throughout the season. At 21 he has the world at his feet and could turn out to be a key player for England and Spurs in years to come.
Left-back | Luke Shaw | Southampton
The talented youngster performed admirably for the Saints last season taking little time to introduce himself to the Premier League. The 17-year-old - dubbed the next Gareth Bale - will reportedly snub interest from Chelsea and Tottenham to sign a long-term deal with the Saints until the summer of 2018.
Centre-midfield | Jack Wilshere | Arsenal
Everyone knows about Jack Wilshere. He's an incredibly gifted football player who plays with great maturity for such a young player. He possesses great leadership skills and could go on to captain Arsenal and England, if he stays clear of injuries he could become a football legend.
Centre-midfield | Oscar | Chelsea
Many doubted Oscar at first in the Premier League because of his small build, but when a player is as talented with the ball as Oscar their frame does not matter. He is part of a formidable Chelsea trio with Eden Hazard and Juan Mata last season, these three can rip teams apart with their play.
Centre-midfield | Philippe Coutinho | Liverpool
Only arrived in the Premier League in January but in the 13 games he played for Liverpool, Coutinho showed what an outstanding talent he is. He unlocks defences with brilliant through balls and excellent dribbling and the 21-year-old could become one of the best players in the Premier League.
Right-wing | Alex Oxlade-Chamberlain
Came to prominence at the age of just 17 and has showed himself to be one of the countries greatest young talents. Plays with great pace and power and is a nightmare for defenders to mark. He also has a great footballing mind and is still just 19 - he can go on to become a footballing great.
Striker | Romelu Lukaku | Chelsea
The Belgian powerhouse had a great season for West Brom, scoring 17 goals. He plays with great power and pace and could become the next Didier Drogba for Chelsea. Jose Mourinho will look to keep him at Chelsea and if he gets game time he could blossom into a great player.
Left-wing | Wilfried Zaha | Man Utd
Zaha is a superb talent and will hope to show the Premier League what he is all about this season when he plays for the Champions Manchester United. At Crystal Palace he did not have enough top level competition to progress as well as he possibly could. He has the opportunity to become a first-team starter for David Moyes' side - ahead of the likes of Ashley Young and Nani - if he gets the chance to shine.
