Kyogo Furuhashi and Yuki Kobayashi have been keeping ticking over ahead of Celtic's return by taking part in a Vissel Kobe training session.
Former Hoops boss Ange Postecoglou snapped up the duo from the J-League club and they've been back to visit during the off-season and even stuck on their old training kit and boots as they picked up an extra fitness session before returning to pre-season with the Scottish champions under the leadership of new boss Brendan Rodgers.
Kyogo arrived at Celtic two seasons ago and has been nothing short of sensational for the Parkhead side. He netted 34 goals last season and scooped all the major personal accolades alongside a domestic Treble with his team-mates. Kobayashi was a January arrival and is still settling into life in Scotland - but did make a number of appearances in the backline.

Vissel Kobe took to social media to upload both images and video of the duo with the caption: "Welcome back."
Both players will be aiming to hit the ground running on their return to Scotland as Celtic look to defend their domestic dominance over Rangers once again. Michael Beale has been busy going through a summer rebuild while Rodgers will likely add a couple of bodies to the champions ahead of the big kick-off.
The SPFL will release the Scottish Premiership fixture schedule on Friday morning with all eyes on the Old Firm dates.
The Hoops also have the luxury of already reaching the Champions League group stage due to their title win meaning they get to avoid those early season qualifiers.
