Manchester United legend Roy Keane has been linked with a sensational return to Celtic as manager but will hope it goes more smoothly than his single season as a player there.
Keane, 49, is currently the favourite to succeed Neil Lennon.
And while he enjoyed his time at Celtic and playing for the “brilliant fans”, he admits in retrospect that he remains EMBARRASSED by this time there.
He told an audience of fans in the Waterfront Hall in Belfast two years ago: “I really enjoyed Celtic even though I done f*** all up there.
“I signed for Celtic in December and physically I hadn’t kicked a ball in two or three months, I’d left United with a broken foot.
“I go straight into a game up there, I tear my hamstring twice. I never justified my role at the club — if anything I’m embarrassed by my time at Celtic.
“What I really enjoyed at Celtic was, it was nice just to be in a different dressing room.
“I had great craic with the United lads but the Celtic boys — Neil Lennon, Petrov, Varga — I really enjoyed the dressing room at Celtic.
“Celtic fans must be looking at me going, ‘you were rubbish’, but it was nice to get a taste of Celtic, brilliant fans.
“But obviously I’m a professional footballer and then the struggle came and I saw the specialist about my hip and I had a year left on my contract.
“I had to go into Celtic every day with my injuries and I was embarrassed. I was ashamed to be going in picking up wages.”
