#4 Zinho Vanheusden (Inter Milan)
Vanheusden is not a household name, and even some of the most passionate Inter Milan fans may not be too aware of the Belgian defender.
He is very much a player who has shown that he has all the raw talent at youth level, and now the question is whether he can transfer that form to senior level. At the moment, that has been delayed because of a cruciate ligament injury picked up towards the beginning of last season.
He moved to Inter at the age of 16, after seven years in the youth teams at Standard Liege. He was involved in the Inter squad as an unused substitute at the end of the 2016-17 season, and in some early games of the next season, suggesting he was going to be given an opportunity in the first team.
However, his progress was stalled slightly because of that injury, and he returned to Standard Liege on loan, where he made his professional debut.
Next season is going to be an interesting one for the 18-year-old. He will want a go in the first team, but he may have to go out on loan again to get it.
