Southampton have identified Romain Perraud as their preferred choice in their search for a new left-back.
Southampton are hopeful of winning the race for the 23 year-old Brest defender who is valued at around £9m.
Newcastle and Leeds have also been linked with a move for the France youth international who has represented his country from under-17 through to under-20 level.
Southampton have been keen to strengthen their full back options for some time and their need for a new left-back has increased with Ryan Bertrand leaving when his contract expires this month.
