Real Madrid, Barcelona and Manchester United are all monitoring the progress of Rennes midfielder Eduardo Camavinga, report L'Equipe.
The 17-year-old has caught the eye with his performances in Ligue 1 and he has even started all 13 league matches for his club to date this campaign, while Atletico Madrid have also been linked.
The player is said to already command a valuation of €30m although he has no plans to exit the French club at this stage of his career.
Camavinga became the youngest ever professional for the club when he made his senior debut on 14 December 2018 at the age of 16 and one month.
He has been a part of Rennes' system since the age of 11 and is regarded to be one of the brightest prospects in French football.
Born in Cabinda, Angola, Camavinga holds Congolese citizenship through his parents. He has lived in France since his second birthday and is said to be currently in the process of acquiring French citizenship.
He celebrated his 17th birthday earlier this week and Madrid officials are said to be considering his incorporation into their Castilla side.
