Celtic are close to agreeing terms on a pre-contract with Arsenal left-back Kieran Tierney.
The 27-year-old, who signed for Arsenal in the last six months, is in talks to return to Glasgow in the summer.
The Hoops are also expected to explore the possibility of taking Tierney on loan until the end of the season, especially if they qualify for the knockout rounds of the Champions League.
Tierney has been told by Gunners boss Mikel Arteta that he can leave the north London club.
He missed the first three months of the season with a serious hamstring injury sustained while playing for Scotland at Euro 2024 and has made just two appearances for the Gunners in the Carabao Cup and FA Cup since returning to fitness.
Asked about the 27-year-old's departure this month, Arteta said: “All the players who are here just want to focus on the impact on the team. If something happens, we will assess it.”
The sky in Italy are reporting that Como are interested in a loan move for Barcelona left-back Alex Valle, who is currently on loan at Celtic.
They understand any move for Valle is dependent on Tierney joining Celtic this month.
Meanwhile, there is currently no agreement on a new deal for current Celtic left-back Greg Taylor, with his contract set to expire in the summer.
Rodgers was silent on Tierney's move
Speaking earlier this month, Celtic boss Brendan Rodgers refused to be drawn on whether he planned to bring Tierney back to Celtic, although he described the Scotland and Arsenal left-back as “one of us”.
“Yes, we will always be associated with top players, especially players who are one of us,” Rodgers said.
“Kieran was instrumental in a really, really successful period when I was here and his talents then took him to another challenge in the Premier League.
“So yes, we will be linked with a lot of names, Kieran obviously, of course because of his situation. But we will only tell you about us when we sign the player, after he signs.”
Why a Celtic return could tempt Tierney
Tierney made more than 170 appearances for Celtic and won five Scottish Premiership titles during his time at the club.
I'm talking to The Currie Club Podcast with Darrell Currie in 2022, Tierney has not ruled out a return to Celtic:
“I think when a player who loves a club leaves, there's always that 'what if he comes back' and you can't rule anything out,” he said.
“I will always love Celtic, I will always support Celtic, so you never know in football.”
