Former Liverpool defender Kolo Toure has arrived in Glasgow ahead of an anticipated move to Celtic.
The 35-year-old was photographed outside Ross Hall Hospital in Glasgow ahead of a medical on Saturday morning.
The Ivory Coast international could now sign for Celtic before they fly out to Kazakhstan on Monday for their Champions League qualifier against Astana.
The ex-Manchester City and Arsenal centre-back will be the second signing made by his one-time Anfield boss Brendan Rodgers since he took over as manager.
Two Celtic central defenders, Jozo Simunovic and Dedryck Boyata, are injured while Efe Ambrose was dropped for the second leg of their triumph over Lincoln Red Imps after his mistake cost the Scottish champions a losing goal in Gibraltar.
Celtic have until the eve of Wednesday's third qualifying round first leg to make one wildcard signing that could feature against Astana.
Toure said he hoped the deal was tied up before that trip . He told Sky Sports News: "It is a privilege to be linked with such a big club and I am just looking forward to it.
"I am a ready for a new challenge. I'm here to try to be ready and help the team as much as I can.
"The Champions League is a great competition and I always look forward to it.
"It's really important, the game coming, to qualify and we will give everything we have got to qualify.
"I plan to work hard every day in training and help the team to get better, that's all I know."
Uruguayan defender Guillermo Varela (pictured in action against Liverpool last season) is set to join Eintracht Frankfurt on a season-long loan from Manchester United.
The Premier League club announced on their website on Saturday morning that they had reached agreement for the player to sign for the Bundesliga outfit until June 30, 2017.
Varela made his senior United bow in a goalless home draw against West Ham last December and made a total of 10 starts for the first team.
He also scored the title-clinching goal for the under-21s last season at Tottenham.
The 23-year-old came on as a substitute in Jose Mourinho's first game in charge of United - a 2-0 friendly win at Wigan last weekend - but did not travel to China for their pre-season tour.

Marseille have signed Aaron Leya Iseka, the younger brother of their departed striker Michy Batshuayi, on loan from Anderlecht.
Belgium international Batshuayi left for Chelsea earlier this month for a reported £33m.
And his 18-year-old sibling, known by their mother's surname, has made the temporary switch to help fill the void.
"I chose Marseille because it is a big club and I want to discover new things," Leya Iseka told om.net.
"It's a dream. I want to make the most of it.
"The supporters are extraordinary, I am desperate to get started at the Stade Velodrome and score some goals.”
L'OM have also been linked with strikers Bafetimbi Gomis and Clinton Njie of Swansea and Tottenham respectively.
Elsewhere, Argentina striker Gonzalo Higuain is understood to be on the verge of a move to Juventus.
The Napoli forward was the top scorer in Serie A last season with 36 goals and has a reported €100million release clause, with the clubs currently in negotiations over the 28-year-old's future.
