Celtic defender Shane Duffy

Shane Duffy has a big problem after seeing his Celtic loan spell cut short with just days of the season remaining. 

That’s according to former Hoops hitman Frank McAvennie, speaking exclusively to Football Insider about Duffy’s ‘nightmare’ loan spell.

Last week, Celtic confirmed Shane Duffy has returned to Brighton after a calamitous period at Parkhead.

Duffy, 29, started his Celtic career with a bang, scoring two goals in his first two games.

However, things quickly soured as a number of error-ridden displays saw the defender relegated to the bench.

Under John Kennedy, Duffy’s game time has been extremely limited with just 102 league minutes to his name since the start of February.

McAvennie claims Duffy must have a problem as he never looked fit at Celtic and tipped him to struggle in his hunt to find a new club this summer.

“It was an absolute nightmare,” McAvennie told Football Insider correspondent Ben Wild.

“He scored two goals right at the start and probably thought Scottish football was easy. 

“Then all of a sudden people started running in behind him and he couldn’t handle it. I would think he’s got a big problem. 

“He never looked fit, he wasn’t getting a game at Brighton. He’s got a few years left on his Brighton contract but I don’t see him playing many games. 

“It’s a shame because I honestly thought he was the man we needed. Someone who could go and win the ball.”

Duffy returns to Brighton with his current deal set to expire in the summer of 2023.

Celtic play their final game of the season on Saturday when they travel to Hibs.
