Ghana captain John Mensah is being monitored by French Ligue 1 side Girondins Bordeaux, according to reports in France.
But Les Girondins must fend off competition from Scottish side Celtic who have also emerged as suitors for his signature.
Bordeaux want to shore up their back line after finishing fifth in the French Ligue 1 last season.
Mensah quit Olympique Lyon this summer over the lack of playing time.
The centre-back also battled injuries last season at the Les Gones after returning from a loan spell at Sunderland.
He made only one appearance for Lyon last term.
