Holland youngster Xavier Mbuyamba is having a trial at Chelsea.
According to Voetbal International, the MVV Maastricht defender is training with the London club to see if he can earn a full time contract.
The 17-year-old is currently with the Dutch second division side, where he is already in the first team.
Since he does not have a professional contract, he is free to decide where he wants to play.
Other teams interested in Mbuyamba include Celtic, Bayern Munich, Liverpool and Porto.
