Ajax sensation Juan Familia-Castillo is set to undergo a trial with Manchester United, Football Insider sources understand.
The teenager, who turns 16 in January, is one of the highest rated players in his age group in Holland.
He is captain of Holland Under-16s and is so highly regarded at the famed Ajax academy that he is playing a year above his age group.
A United academy source has told Football Insider that the club have offered Familia-Castillo a trial to lure him to Old Trafford.
The Premier League giants are increasingly hopeful of agreeing a deal for the youngster, who they have been closely monitoring for 18 months, but are aware that Ajax will not let him go easily.
Familia-Castillo plays regularly for Ajax Under-17s even though he is still only 15 and United scouts have been impressed by his progress.
The youngster can play central or left midfield and is renowned for his technique and passing range.
