Celtic chairman Brian Quinn today told manager Martin O'Neill that cash to spend on new players was "limited".
O'Neill, who won the treble in his first season at Parkhead, yesterday predicted that such news would come from the plc.
And today the Celtic chief's fears were realised ahead of the next financial results which are published in February.
Quinn told the Celtic View: "We have recently indicated that the amounts available to strengthen the football division further this season are likely to be limited.
"Nevertheless, the board will listen and consider any request that Martin might make and give it consideration."
Quinn revealed that player costs increased by 36 per cent last year.
O'Neill has brought in John Hartson, Steve Guppy, Momo Sylla and Bobo Balde this season for a combined fee of nearly Stg£10million.
