Ligue 1 clubs Nantes and Strasbourg are interested in signing Mikel Agu from Portuguese side Vitoria Guimaraes.
According to Footmercato, Nantes have tabled a €1.5m offer for the midfielder.
Vitoria Guimaraes are willing to sell the Nigerian international but want the French club to increase their offer.
Lorient and Nimes have also shown interest in the talented midfielder.
The 27-year-old has scored once in 16 league appearances for Guimaraes this season.
Agu joined Guimaraes on a permanent deal from FC Porto last summer.
He previously spent time on loan with Club Brugge, Vitoria Setubal and Bursaspor.
