Chelsea are eyeing Olympique Marseille defender Boubacar Kamara.

The captain of the French club's reserve team is also being watched by Borussia Dortmund and Paris St Germain.

Marseille want Kamara to sign a three-year deal.

The Sun says OM are severely hampered by the fact that he does not have a professional contract.

Marseille will therefore be helpless in preventing the youngster from leaving should he receive a lucrative offer.

Chelsea would appear to be favourites to land Kamara given that he is said to favour a move to the Premier League. And PSG are scarcely renowned for bringing through youngsters.
