Celtic could face years of playing catch-up to Rangers if the Parkhead board continue to hold off on the rebuilding process, according to Alan Hutton.

Speaking exclusively to Football Insider, the former Gers defender admitted it was alarming to hear the Hoops’ decision-makers still have no plan in place for the summer and beyond.

In a statement issued on Monday, Celtic chairman Ian Bankier confirmed the club’s review of management and the structure at Parkhead, which was first announced in early December, was still ongoing.

While Peter Lawwell’s end of season departure has been announced, there has been no news on the future of manager Neil Lennon after a disappointing season at the helm.

The Bhoys, who started the season in pursuit of their 10th successive league title, currently sit second in the Premiership table, 18 points behind Rangers.

Hutton has warned Celtic they face a slow process to get back to where they want to be and insisted the delays at the top would not help their cause at all.

Asked if Celtic fans should be worried by the news of the review, Hutton told Football Insider assistant editor Russell Edge: “Yeah, I think they would be. The longer they wait, you wonder, well, when are they going to get down to their business? 

“When are they going to start this whole process, because it takes time – you just have to look at Rangers, their situation, it’s taken Gerrard two seasons to get to where they want to be.

“It doesn’t happen overnight, you can’t do it in one transfer window unless you’ve got Man City money to go and absolutely splash the cash and get the people that you want and get the people that you want to leave. 

“It’s going to be a kind of slow process and it can take a couple of seasons for them to get back to what we know as a challenging team.

“Rangers at the moment are only getting stronger, Celtic seem to be on the decline.”

In other news, Hutton cannot believe what he say from Shane Duffy and Kristoffer Ajer versus St Johnstone.
