Real Madrid midfielder Thomas Gravesen is expected to confirm his £2m transfer to Celtic in a statement due to be released on Wednesday afternoon.
The 30-year-old left Glasgow on Tuesday without signing after two days of talks and a medical.
It prompted claims that Celtic were concerned about an old knee injury.
But Gravesen’s agent, John Sivebaek, told BBC Sport on Wednesday: “We will be issuing a statement in three or four hours. I have no more to say.”
Celtic reportedly remain confident of completing the deal, although Gravesen has revealed four English Premiership clubs – Newcastle, Bolton, Everton and Middlesbrough – were interested in his signature.
It had been thought that personal terms and a £2m transfer fee had been agreed, but Celtic now say “talks are ongoing”.
Gravesen left Glasgow to join the Denmark international squad on Tuesday without a decision on his future being announced.
The Dane left Everton for Spain in a £2.5m deal in January 2005 and had been made available for a £2m fee.
He hopes to have a new club before Thursday’s transfer deadline and Denmark’s opening match of the Euro 2008 qualifying campaign.
They are due to play an international friendly against Portugal on Friday before they start on the road to Euro 2008 away to Iceland on 6 September.
The Danish squad was to assemble on Sunday, but national coach Morten Olsen gave Gravesen time off to secure a new club.
Former Celtic player Tommy Burns, now head of youth development, believes Gravesen would be a great signing.
“He has got a great pedigree,” Burns said.
“He played in the English Premiership and made a big impact there.
“He went to Real Madrid and maybe didn’t make so much of an impact there because they obviously have so many top players.
“But I don’t think there is any doubt that, if Celtic get him to come here, he would make a huge impact.”
Meanwhile, sources suggest that Newcastle’s interest in Gravesen has cooled.
