The 16-year-old made seven first-team appearances for Rennes during the 2018-19 campaign and has featured on a further seven occasions in the early stages of this season.
Last week, it was alleged that AC Milan had joined the likes of Arsenal and Tottenham Hotspur in the race to sign the midfielder, who impressed in his team's 2-1 win over Paris Saint-Germain earlier this season.
However, according to Marca, Madrid are also interested in Camavinga, with the Spanish giants already watching him on a number of occasions as they consider a swoop.
The youngster signed his first professional contract with Rennes in the latter stages of 2018; the deal runs until 2022, although it is unclear whether a release clause was included.
Camavinga has played every minute of his team's 2019-20 Ligue 1 campaign thus far, and he also featured in Thursday's 1-1 draw with Celtic in the Europa League. body check tags ::
