Number 10 and Striker
If you've caught any of Barcelona's last couple of games, you'll notice some unfamiliar names on the starting line-up. Among them are Carles Perez (21), and Anssumane "Ansu" Fati (16).
The 16-year-old has been particularly impressive as Barcelona look for a creative spark in the temporary absence of Lionel Messi. With impressive performances in the last couple of games featuring a goal in each, the comparisons are already flying in with the Argentine superstar.
Ernesto Valverde is eager to shield him early on in his career though and manage expectations. Regardless, his technical adeptness and ability to beat players in close spaces is excellent and he could be a big player in the future for this side.
Although he came to the spotlight at Paris Saint-Germain, Timothy Weah (19) has since made headlines in Scotland with Celtic and has now earned a permanent move to Lille. Although he's only sparingly making appearances for them now, Lille have a long campaign ahead of them and Weah will have to take every opportunity to make his mark in this Lille side packed with talent.
