Chelsea are tracking Paris Saint-Germain youngster Abdourahmane Barry, according to Sky sources.
The 17-year-old defender is being watched by a number of top European clubs.
Bundesliga side Wolfsburg are also understood to be showing interest in the PSG U19 player, whose contract expires in June this year.
Transfer Talk: Can Arsenal land Auba?
The Transfer Talk panel discuss whether Arsenal can clinch a deal to sign Pierre-Emerick Aubameyang.
Barry is a similar profile to former PSG youth centre-back Dan-Axel Zagadou, who switched to Borussia Dortmund last summer.
Zagadou played in both of Dortmund's Champions League group-stage defeats by Tottenham earlier this season.
Paris-born Barry is primarily a centre-back but can also play at right-back and defensive-midfield.
