Gordon Strachan is expected to be appointed Scotland manager at a lunchtime press conference at Hampden Park.
Strachan has been the overwhelming bookmakers' favourite to take the job since Craig Levein was sacked in November after a poor start to Scotland's World Cup qualifying campaign.
The former Celtic boss, who won 50 caps for Scotland, has been out of management since leaving Middlesbrough in October, 2010.
With Scotland's chances of qualifying for the 2014 World Cup effectively over, it seems likely the 55-year-old will be given a contract through to 2016.
Strachan's first match in charge will be a friendly against Estonia at Pittodrie on 6 February, before a World Cup qualifying double-header in March.
Scotland host Wales at Hampden on 22 March and face Serbia away four days later.
Strachan, who at times had a fractious relationship with the media while at Celtic, has made no secret of his desire to manage the national side.
"It's quite simple really, it would be an honour to be asked to be the manager of your own national side, it's terrific," Strachan told ITV in November.
"I could sit here and say 'yes, it would be great' or 'no, it's not for me' but it would also be arrogant of me to answer that if nobody has asked you and presume that someone will ask."
