Celtic should complete the signing of former Liverpool defender Kolo Toure on Saturday.
The 35-year-old worked under Brendan Rodgers at Anfield and comes in to provide much needed defensive cover.
If he passes a medical, he should be available for Wednesday’s Champions League qualifier against FC Astana.
Toure, who played 26 times for Liverpool last season, would become Celtic’s second summer signing after the arrival of Moussa Dembele.
The deadline for signings ahead of Wednesday’s third round Champions League qualifier was 21 July, but clubs are allowed one “wildcard” signing up to 24 hours before kick-off.
Toure, who has been capped 118 times by the Ivory Coast, arrived in British football at Arsenal in 2002, becoming part of the club’s famous “Invincibles” side who remained unbeaten en route to winning the 2004 Premier League title.
He joined Manchester City for £14m in 2009, winning another Premier League title in 2012, before Rodgers took him to Liverpool in 2013.
