- Kylian Mbappe | €192.3m (£171.5m/$223.6m)
After his impressive debut season at PSG and his role in France winning the World Cup in Russia, where he was named the tournament's best young player. The forward initially joined PSG on loan from Monaco before the deal was turned into €180m (£160m/$209m) permanent arrangement.
2.Marcus Rashford| €89.2m (£79.6m/$103.7m)
Rashford may still be trying to convince Jose Mourinho to start him on a regular basis at Manchester United, but he has risen five places in this list from 12 months ago and also added nearly €50m (£45m/$58m) to his value. He showed flashes of his brilliance for England at the World Cup and will now look to become a fixture in United's starting line-up.
- Gabriel Jesus | €88m (£78.5m/$102.3m)
The striker's value has almost doubled over the past 12 months and he continues to boast an impressive goalscoring ratio for Premier League champions Manchester City. He did endure a frustrating World Cup, but that is likely to be only a blip in what should be a fruitful and goal-laden career.
- Ousmane Dembele | €84.3m (£75.2m/$98.3m)
Down a place from 12 months ago, Dembele nevertheless has seen his value rise from €60.9m (£54.3m/$70.8m) after he joined Barcelona from Borussia Dortmund. Dembele took time to find his feet at Camp Nou before a positive end to the campaign saw him win La Liga and be part of France's World Cup-winning squad.
5.Malcom | €64.6m (£57.6m/$75.1m)
One of the stars of Ligue 1 last season, Malcom came close to leaving Bordeaux in the January transfer window when he was targeted by Arsenal and Tottenham. The Brazilian winger is again a wanted man, with Everton and Inter Milan both keen on a summer deal.
