Rennes have reportedly placed a €60m (£53m) valuation on midfielder Eduardo Camavinga.
The 17-year-old has been in impressive form for his French club during the 2019-20 campaign, contributing one goal and two assists in 36 appearances in all competitions.
The France Under-21 international is widely regarded as one of the best young talents in world football, with a number of clubs believed to be monitoring his development.
Real Madrid continue to be strongly linked with a summer move, but according to Mundo Deportivo, Zinedine Zidane's side will have to come up with an offer of €60m (£53m) to sign the midfielder.
Camavinga, who has also been linked with Barcelona and Liverpool, has a contract at Roazhan Park until the end of the 2021-22 campaign.
Rennes boss Julien Stephan recently urged the youngster to reject a summer move in order to continue his development at the club.
