Galatasaray have opened talks with Lille over a summer move for Aurelien Chedjou.
The 27-year-old Cameroon international defender has recently been linked with Valencia.
However, Turkish champions Gala are closing in on a switch for the centre-back after announcing to the Stock Exchange that discussions over a transfer had begun.
Chedjou joined Lille from Rouen in 2007 following a two-year spell with Auxerre.
