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.
