Celtic are being linked with a swoop for Djurgardens left-back Keita Kosugi.
The Hoops are one of a number clubs said to be interested in the Japanese left-back, who has only been in Sweden for around a year, reports Sponichi Soccer.
The 19 year old impressed in DIF's Allsvenskan campaign last season as well as during their Conference League campaign.
After signing last year, he initially went in as back-up to Samuel Dahl and didn't get a lot of game time. However, he became a mainstay after Dahl's switch to Roma and went from strength to strength.
Kosugi came through at Shonan Bellmare and hadn't yet made his first-team breakthrough before moving to Sweden in 2024.
He is capped for his country at under-17s, 19s and 20s level.

PSG and Atalanta are also believed to be interested so Celtic could find it tough if they do decide to attempt to land the player.
His club stunned Europe by reaching the semi-finals of the Conference League despite being unfancied but weren't able to make it past Chelsea to reach the final, losing 4-1 in the first leg and then 1-0 in the second.
Speaking afterwards, the teenage full-back admitted he found Noni Madueke too hot to handle.
He told FotbollSkanalen: “I couldn’t do anything to Madueke. He was so good. I tried to stop him but he created a lot anyway.
"He’s one of the best wingers in the Premier League, so it’s difficult to face him. But if I want to get there (to that level) I have to develop a lot.”
Celtic are likely to need a new left-back with Greg Taylor looking set to depart on a free transfer, with the offer of a new contract remaining unsigned.
Kieran Tierney is coming in on a free transfer but with Jeffrey Schlupp's loan ending, the homecoming hero would be the only option in that position as it stands.
Talks have been held with Schlupp over a possible permanent deal, his own deal at Crystal Palace up.
