Whelan: Celtic tipped to sign defensive powerhouse after confirmed development

Noel Whelan has tipped Celtic to sign a strong and quick defender to replace Shane Duffy.

Speaking exclusively to Football Insider, the ex-Aberdeen striker delivered his verdict after Duffy’s disastrous loan spell was cut short.

Football Insider revealed on Thursday (6th May) that the defender would not play for Celtic again and he later confirmed he had returned to Brighton &Hove Albion.

The 29-year-old played 27 times across all competitions for the Hoops but did not feature after Neil Lennon resigned as manager in February.

“It’s been a disaster,” Whelan told Football Insider correspondent Dylan Childs.

“They took a chance and it’s not worked out. He’s not covered himself in glory with some of the performances he put in up there.

“With the sacking of Neil Lennon, or him walking away whichever way you want to put it, that opportunity of him singing permanently has gone.

“There are a lot of loan players there are going to go back to their parent clubs given the season they’ve had and whoever the new manager is will not pursue them.

“It’s safe to say there’s no question mark over Duffy. He’s not done enough and not been good enough. He’s shown fragility at the back that a team like Celtic can’t have.

“They need stronger players, quicker players and better quality players, unfortunately. I expect them to sign a new defensive powerhouse.

“I’m sure Shane Duffy will find another club somewhere and hopefully that will suit him better.

“He’s shown that he’s not up to the job at Celtic.”

Football Insider understands Wayne Rooney’s Derby County are interested in signing Duffy if they are in the Championship next season.

They survived relegation on the final day but are currently embroiled in a legal battle that could see them hit with a points deduction.
