Noel Whelan has backed Dermot Desmond to make big changes behind the scenes at Celtic after what has been a “catastrophic” season.

The former Leeds United and Aberdeen striker, speaking exclusively to Football Insider, believes there are problems from top to bottom at Celtic Park and that it is time for a shakeup in Glasgow.

As revealed by Football Insider this week, the major shareholder is plotting a major boardroom reshuffle that could begin with his financier son Ross Desmond in an executive role at Parkhead.

On the footballing side of things, recruitment chief Nicky Hammond is understood to be under “major threat” of being sacked while Neil Lennon’s position also looks at risk.

Whelan insisted that while the main issue has been performances and results out on the field, a change at the very top may also be needed.

Whelan told Football Insider: “This season has not been great on the field, has it? I mean they might expect to be first or second but saying that, you’re expected to be a lot closer to be first with Rangers.

“This season has just been really catastrophic for them in terms of results against smaller sides when really, when you look at Rangers, they’ve gone about it in the right way, they’re winning the games and rightly so. That’s expected because you’re Glasgow Rangers and Celtic.

“Fans have been asking for the manager’s head after the bad run the games, so far behind in the points, I think the board probably needs to be stronger, I know Neil Lennon has been there a long, long time but maybe change is needed throughout Celtic as well.”

Celtic, who have picked up nine successive league titles, currently sit 21 points behind Rangers in the Premiership title race.

They have lost both games to their Glasgow rivals so far and were knocked out of the Europa League groups stages with just one win under their belts.
