5 Ligue 1 youngsters destined for big future transfers

#2 Youri Tielemans (AS Monaco)

There's no doubting Tielemans' ability. After all, it was he that rejected several other clubs to sign for Monaco last summer, with a €25m (£21.9m) transfer fee being agreed.

It was a gradual transition that followed, learning new responsibilities with teammates and a manager who was deploying him in deeper midfield positions than during his final campaign with Anderlecht - where he scored 18 goals and created 15 assists across all competitions that year.

Tactical discipline, understanding teammates' tendencies and dealing with a knee injury of his own were all challenges that the Belgium international has embraced, though his stock has continued to rise, albeit at an under-the-radar pace on the French Riviera.

He's played slightly further forward at times this term and already has two league goals from those positions, doubling his goalscoring tally in the final third from the entirety of last season, which speaks volumes.
