Celtic have given a permanent contract to Scottish Cup final match-winner Jean-Joel Perrier-Doumbe until the end of the season.
Jean-Joel Perrier-Doumbe scored the winner in the Scottish Cup final
The 28-year-old Cameroonian right-back had been on loan at Celtic from Rennes in the second half of last season.
But negotiations fell through at the start of the summer because Rennes were demanding a £400,000 fee as a result of the terms of the loan spell at Celtic.
Perrier-Doumbe did not win a contract after a trial with Sheffield United.
The Blades would have been able to sign the free agent without a fee being paid.
Celtic didn't put in an offer and I now know that PSG are no longer looking for a right-back

And negotiations re-opened with Celtic this week.
Perrier-Doumbe arrived at Celtic Park from Rennes in January and broke into the side near the end of the season following injuries to Mark Wilson and Gary Caldwell.
He scored the winning goal in the Scottish Cup final against Dunfermline Athletic in his last appearance for Celtic.
News of Perrier-Doumbe's renewed negotiations came as Frenchman Bernard Mendy revealed that Celtic had not followed up reported interest in signing him from Paris St Germain.
"I've got a year on my contract here and that's all I know, so I've just concentrated on the start to our season," Mendy told The Sun.
"Celtic didn't put in an offer and I now know that PSG are no longer looking for a right-back. So the idea is now to stay in Paris.
"With Paul Le Guen and Yves Colleu in charge, we can do something at this club."
