Released Liverpool defender Kolo Toure is in talks with Celtic.
The Daily Mail says Toure is in Glasgow today for signing talks with Celtic.
The 35-year-old has undergone a medical and, if he signs, would be available for Wednesday's Champions League first leg qualifier against FC Astana.
Toure, who worked under Brendan Rodgers at Anfield, would be Celtic's second summer signing after the arrival of Moussa Dembele.
