Willo Flood has opened discussions with Celtic in regards to a proposed move to Parkhead.
The midfielder, who is currently on loan at Dundee United, has been given permission to speak to the Glasgow giants by his parent club Cardiff.
He spent Thursday with Hoops officials, hoping to thrash out a deal which will allow him to join the reigning SPL champions.
Celtic boss Gordon Strachan has made no secret of his desire to strengthen during the January transfer window and will be delighted to have inched closer to sealing a move for Flood after missing out on the West Ham-bound Radoslav Kovac.
The experienced coach accepts that Scottish clubs find it difficult to compete with their English counterparts, but remains confident that his search for new recruits will bear fruit.
"It's very hard sometimes," Strachan said.
"I would rather not just grab anyone to try and appease people.
"If they come along, they have to be of value to us.
"We are trying to do that at the moment but it's not an easy market out there.
"We cannot deal in England and everybody wants to get to England, so we've got a problem."
Strachan added: "I'm trying to get business done and I think that would be good because I think our signings in the January window have been important to us in the last few years.
"Roy Keane was a great signing, a great presence to have about the place.
"Paul Hartley came in and did a smashing job. Then Robbo (Barry Robson) last year with Andy Hinkel - Robbo was terrific last year.
"So we're hopping if we do sign people, they will be important for us."
