According to reports, the Hoops and Arsenal have verbally agreed for Tierney to join on a free transfer. They are currently awaiting word on whether Arsenal will permit him to go on loan for the remainder of the season.
According to Romano, Tierney, who Kenny Miller has called “world-class,” would join Celtic following the season when his contract at the Emirates expires if the Gunners do not allow the Scottish full-back to depart in January.
Given Oleksandr Zinchenko’s possible exit in the coming days, Tierney, who has participated in two of Arsenal’s previous three Premier League games, might remain a backup option until the end of the season.
The Ukrainian full-back is reportedly being eyed by Borussia Dortmund and Atletico Madrid, and his exit could prompt Mikel Arteta to keep Tierney for the remainder of the campaign.
The 27-year-old spent last season on loan at Real Sociedad but was forced to miss a large part of the campaign due to multiple setbacks and made only 14 starts in La Liga as a result.

Celtic’s winter business has gathered pace in recent days as the Hoops parted ways with Alexandro Bernabei and Kyogo Furuhashi, while Stephen Walsh and Odin Thiago Holm left on loan.
The Scottish giants are reportedly looking to bolster their frontline further after welcoming Jota back on a five-and-a-half-year contract and have now set their sights on Norwegian winger Sondre Orjasaeter.
According to Sky Sports, Celtic is eager to complete the deal before the transfer deadline next week and have made an initial bid for the 21-year-old forward.
