St Etienne captain Julien Sable could be set to follow former manager Elie Baup to Toulouse.
Sable is thought to be unhappy with Les Verts officials for allowing Baup to leave the Stade Geoffrey-Guichard and could be set to follow him out of the door.
Baup is keen to link up with the midfielder in Toulouse and has spoken with the player about a move.
Sable visited Toulouse's facilities on Tuesday to discuss a transfer, despite new St Etienne coach Ivan Hasek's desire to keep the midfielder.
Meanwhile, St Etienne striker Sebastien Mazure has reached an agreement to rejoin former club Caen, according to reports.
Mazure struggled to make an impression in Ligue 1 last term, scoring just one goal.
