Rennes will allegedly demand €50m (£42.95m) if any clubs express an interest in Eduardo Camavinga.
Despite having only turned 17 earlier this month, the midfielder has established himself as a first-team regular at the Ligue 1 outfit.
According to L'Equipe, Rennes have placed a firm valuation on the teenager's services should they receive any offers during the January window.
While Camavinga still has over two-and-a-half years remaining on his contract, there is seemingly an acceptance from Rennes that they must be realistic regarding any potential sale.
The France Under-21 international has made 16 appearances in all competitions this season.
