Chelsea lead the race to sign highly-rated Dutch 18-year-old Xavier Mbuyamba from Barcelona, according to his agent.
The Dutch centre-back has earned rave reviews and even been compared to a young Virgil van Dijk.
He joined Barcelona from MVV Maastricht last summer but his agent is already searching for the best top side to continue his development.
The starlet's representative, Carlos Barros, told Voetbal International: '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.
