The 30 year old was released from his Wigan Athletic contract by mutual consent at the end of last season after enduring an unsuccessful time with the club.
Speaking about his potential move to the Scottish side, Kapo said: "Several clubs have been in touch with me over the past few weeks but nothing came to me as strong as Celtic.
"I am aware of the track record of Celtic. They are one of the big clubs of European football and I would see this as a huge challenge. "I am happy with that and, in fact, Celtic are more than just a football club. I'm aware of the spirit of the club and I have noticed already the feeling connected with them." If all goes as expected, the former Birmingham City and Juventus man is expected to sign for the hoops within 24 hours.
