Scotland assistant manager Terry Butcher has urged James McFadden to remain at Birmingham City.
On Sunday, McFadden's agent confirmed the Scotland striker is keen to leave St Andrews following the club's relegation to the Championship.
Celtic are reportedly interested in the 25-year-old, who only signed for Birmingham in January from Everton.
However, Butcher, who worked with the forward during his time at Motherwell, feels it would be in McFadden's best interests if he were to stay with Alex McLeish's side rather than make a summer move to one of the Old Firm clubs.
"Give it time and that move will maybe happen for him one day," Butcher told the Scottish Sun. "I suspect it probably will. I just don't think that time is right now.
"I just think the way he goes about his business as a Birmingham City player helps unite all the Scotland fans.
"If you play for one of the Old Firm there will always be people, no matter what you do, who won't like you."
