The Frenchman looks set to join Swansea this summer after the Welsh club failed to prise him away in January.
Former France Under-21 international Franck Tabanou is on course to be Garry Monk’s second summer signing - after the arrival of fellow Ligue 1 star Andre Ayew - as he looks to improve a squad that achieved Swansea’s record Premier League points tally last season.
Swansea failed to secure a deal for Tabanou in January and BBC Sport reports that Saint Etienne have upped their asking price from £3 million following a strong end to the season for the left-sided player.
Tabanou seems enthusiastic about the move with his agent, Philippe Lamboley, previously stating to the BBC: "He has chosen Swansea, he has told me he is not interested in any other offers from any other clubs."
What will he bring to Swansea?
Left-back is an area that needs strengthening after the departure of Ben Davies to Spurs last season and Tabanou’s arrival will provide stiff competition for Wales international Neil Taylor.
The 26-year old’s ability to play in a more advanced role on the left also adds versatility to the squad.
His arrival, if completed, will reunite him with his former Saint Etienne team-mate Bafatembi Gomis, who rose to prominence last season at The Liberty Stadium.
