If being a promise is difficult, achieving the breakthrough is even more complicated.
Many players see the 2017-18 season as an opportunity to become a top football player in Europe.
Kylian Mbappé had an impressive start in 2017. He was one of the main contributors to AS Monaco winning the Ligue 1 title. However, this season he must establish himself to be considered one of the best in the world.
The same goes for Gabriel Jesus. The Brazilian arrived at Manchester City and made a big difference. Unfortunately, injuries didn't allow him to have the desired regularity. This is his season.
