Chelsea could lose 16-year-old winger Samuel Iling-Junior in the summer, with Juventus being the latest club to join the race for his signature.
Paris Saint-Germain are another major contender to sign Iling-Junior, with Bayern Munich, Ajax and Schalke also rumoured to be interested.
The Blues are keen to tie the England Under-17 international to his first professional contract but are concerned that he could be tempted to leave.
The 2019-20 season marked the breakthrough campaign for the forward, who is considered to be one of the best in his age group having impressed in Ed Brand’s Under-18s team.
Borussia Dortmund have been linked with making a move for Chelsea’s other top attacking talent from the same age group, Charlie Webster, who the west Londoners are looking to sign onto professional terms.
Chelsea are, however, more confident about renewing Webster’s deal, with the 16-year-old set for a prominent role under Brand next season.
Frank Lampard has already given eight debuts to academy stars from the club’s Cobham training base this season and it is hoped that the new direction from the manager might help retain more talented youngsters.
