Chelsea have reportedly declared an interest in signing Marseille teenager Boubacar Kamara.

Despite being aged just 16, Kamara already holds the captaincy of the reserve team but he is yet to sign his first professional deal at the Stade Velodrome.

According to RMC, that has encouraged Chelsea to make a bid for the France Under-18 international, although the Ligue 1 giants have moved to offer the defender a three-year contract.

It has also been claimed that Borussia Dortmund are keeping tabs on the player.
