Here we take a look at three players from Chelsea who have been key to them reaching the final.
Born in Camden, north London, Mola, pictured above left, can play as a left-winger or left-back. He joined Chelsea as an Under-14 player.
An England Under-17 international who turned 17 this month, Mola has made four U18 Premier League Cup appearances and has scored twice in 11 U18 league outings in 2017/18.
Signed from Ipswich Town in 2016, the 18-year-old forward, above centre, has been prolific in his two seasons at Chelsea.
Brown scored 10 goals from five U18 Premier League starts last season, including four as a substitute against Brighton & Hove Albion.
In 2017/18, Brown has 10 goals from 15 league appearances as well as three in the Cup.
The 16-year-old midfielder, above right, joined from Rangers in the summer and has established himself as a regular in the Blues' U18s.
The Scotland Under-17 international has appeared in four U18 Premier League Cup matches, and has five goals from 13 league matches.
