Celtic must keep hold of their star players this summer if they are to close the gap on champions-elect Rangers.

That is according to ex-England goalkeeper Paul Robinson, speaking exclusively to Football Insider after Celtic posted £5.9million losses for the six months to December 2020.

Celtic made a profit of £24.4m over the same period in the previous financial year, though that was boosted by the £25m sale of Kieran Tierney to Arsenal.

Overall revenue was down 23.7% as the club continues to feel the impact of the coronavirus pandemic.

Football Insider revealed on Monday that the club are planning for at least two big-money player sales in the summer to stem the losses and get the club back on a sure financial footing.

But Robinson claims it isn’t a foregone conclusion that Celtic will look to sell big-name players.

He told Football Insider correspondent Dylan Childs: “We don’t know for sure. There are different ways of financing things with the climate that we’re in.

“I don’t expect many people to be making a profit in any business in any way, shape or form at the moment.

“There are ways of getting around it, refinancing debt, borrowing from Peter to pay Paul, so to speak.

“Whether they decide to sell one of their big players is yet to be seen.

“It wouldn’t exactly be a last resort because we’ve seen them do it before. But I think if they are to try and close this gap to Rangers next season, they’re going to need to keep their best players together.”

In a club statement, Chairman Ian Bankier warned that things would get worse before they get better: “Looking forward, the football and financial environment is still volatile and very uncertain because of the ongoing effects of Covid-19.”

“Trading seasonality means that financial performance in the second half of the financial year will be lower than the first half.
