Josh Doig, a 23-year-old Scottish defender, has previously been considered by Celtic, but it seems unlikely that he would agree to serve as a backup to Kieran Tierney at this point in his career. The club is currently without a natural substitute for Tierney, prompting manager Brendan Rodgers to frequently rely on Liam Scales for backup, which underscores the urgent need for reinforcements in the left-back position. While Doig's skills are acknowledged, his desire to secure a starting position might not align with the current setup at Celtic, where Tierney is the preferred choice. Doig is under contract with US Sassuolo until 2028 and, as per Transfermarkt, is valued at €5.00m. He has also drawn interest from other Italian clubs, including Juventus and Venezia.
