Le Mans midfielder Moustapha Bayal Sall is a target for Portsmouth.
The Daily Mail says Pompey boss Harry Redknapp has had the St Etienne centre back, who can also play in midfield, watched several times, most recently in his side's 4-1 win over Le Mans on Saturday.
The 6ft 4in, defender, who is rated at £3million, has a year left on his contract. But he is seeking a considerable pay increase and his club may cash in on him during the summer.
