Scottish giants Celtic are reportedly keeping tabs on Derby County left-back Lee Buchanan ahead of the January transfer window.
Head coach Ange Postecoglou is keen to bolster his options at full-back, as the Hoops currently have Greg Taylor ruled out due to injury.
The Australian has used five difference players at left-back so far this campaign, including right-back Josip Juranovic, who was forced to play on the left side in Celtic's 2-0 Premiership victory at home against St Johnstone on Saturday.
According to The Sun, Celtic have been tracking Buchanan for some time, while chief scout Mick Doherty went to watch the 20-year-old play for the Rams last week.
Buchanan will see his contract at Pride Park expire next summer, so Derby may consider selling the youngster to generate some funds.
The England Under-21s international has started eight of Derby's 12 Championship game so far this season, including yesterday's 1-1 draw against Coventry City.
