The money generated from that run has offset the disappointment of the early Champions League exit to FC Basle in August.

But Quinn insists “wholesale changes” are not envisaged at the club.

He said: “We will be sitting down very soon with Martin to find out what his requirements are.

“Obviously we are better placed to do this than we would have been if we had not gone to the UEFA Cup final.

“I must point out, however, that to suggest wholesale changes are needed could be seen as something of a slight to the players who have brought us so much success this year.

“We played 60 games with energy, skill and determination that illustrates the excellent playing squad we have.”

Quinn added in the Celtic View: “We believe it is right to continue to seek the correct balance between football success and financial prudence.

“The wreckage amongst football clubs, not only in Scotland but also across Europe, shows how easy it is to get into serious financial difficulties while sustaining real challenges on the football field.

“Celtic’s investors and supporters have provided the money to keep our club performing at a high level and I believe we have an obligation not to squander those resources.”

But Quinn is confident the fans will understand the financial balance the club wants to strike.

He said: “Fans increasingly recognise the duty of the board to get the balance right.

“Football is going through a very difficult time and steering a club such as ours through the financial rocks is a difficult job.

“We are not obsessed, as some commentators suggest, with getting our debt down to zero.

“But we cannot rely on a run in Europe such as we have just had in drawing up our financial plans.”
