Kieran Tierney may have to watch boyhood club Celtic from afar nowadays.

But that hasn't stopped the former Hoops defender getting the inside track on his old team.

The Scotland international admits he's been dazzled by Ange Postecoglou's fusion of Japanese talent within the ranks of the Scottish champions.

The £25million left-back has been well-placed to find out all about the Asian football stars brought to Parkhead, the majority of whom have taken the Premiership by storm.

Arsenal team-mate and Japan international Takehiro Tomiyasu has told KT all about Celtic's new players.

The Hoops have six Japanese players. They are Yuki Kobayashi, Yosuke Ideguchi, Tomoki Iwata, Reo Hatate, Kyogo Furuhashi and Daizen Maeda.

Only Ideguchi has failed to make an impact and looks set to leave the club after just one year. 

While Kobayashi is starting to settle into the first team and Iwata made his debut against Morton on Saturday.

Thanks to Tomiyasu, Tierney has all the info he needs on each of them as a diehard Celtic fan.

He told the Scottish Sun: “I speak to Tomi a lot. I didn’t know much about the boys who came in from Japan before and it’s the same with the two signed over the last month.

“I don’t see the J-League and so I’ve been asking Tomi for info and his thoughts on them as players.

“Daizen Maeda was with Tomi in the Japan squad for the World Cup in Qatar.

“Tomi’s been very positive about all the boys signed and that’s been good to hear. He’s a great player himself and an excellent team-mate. He’s good company.

“I’m always speaking to Tomi and if ever there’s a Celtic game on at the training ground he sits and watches it with me. I’ve tried to make him a Celtic fan!

“It’s funny, but Tomi’s seen that old video of me being presented with boots by Shunsuke Nakamura when I was just a kid at Celtic. He was aware of it a long time ago.

“Nakamura was one of Tomi’s heroes growing up, but that goes for so many of the Japanese players all over the world.”
