26-year-old Valenciennes forward Nuno da Costa is soliciting interest from various corners of Ligue 1, according to L’Équipe.
RC Strasbourg, FC Metz, Bordeaux and FC Lorient (now in Ligue 2) have all positioned themselves.
Les Grenats will accelerate their interest if they do not succeed in securing a second loan deal for Osmanlispor striker Cheick Diabaté.
