Chelsea have emerged as the favourites to sign Barcelona prospect Xavier Mbuyamba, according to the player's agent.
While Mbuyamba has three years remaining on his contract, it has been suggested that the 18-year-old could move to another high-profile club in the future.
Carlos Barros, the centre-back's representative, has hinted that the Blues are currently ahead of the likes of Real Madrid in the race for the Netherlands Under-19 international.
Speaking to Voetbal International, Barros said: "Almost all major clubs in Europe have asked about Xavier. Real Madrid are also there, they are serious about their youth system, but that would of course be a sensitive switch.
"Juventus and Inter are interested, as are top clubs from Germany and England. Chelsea have the best papers. Of course we discussed this extensively last year.
"Chelsea gave a fantastic presentation. There is a unique football atmosphere there. You immediately sit with the first-team players during lunch and the club has outlined a very ambitious plan for Xavier."
Mbuyamba made three outings for Barcelona in the UEFA Youth League earlier this season.
