It is a new era under Ange Postecoglou at Parkhead.
Tasked with leading an embattled Celtic back to the Scottish summit, having been dethroned by bitter rivals Rangers last season, Postecoglou is slowly putting his stamp on the club.
Prised from Yokohama F.Marinos after ending the club's 15-year J1 League title drought in 2019, Postecoglou has returned to Japan to raid Andres Iniesta's Vissel Kobe for Kyogo Furuhashi.
Postecoglou knows Furuhashi well from their time together in Japan, where the 26-year-old forward has starred since arriving from second-tier outfit FC Gifu in 2018.
Regarded as one of the country's most exciting talents, the Japan international brings plenty of goals, pace, creativity and dribbling ability to Glasgow, with Celtic fans hoping he can follow in the footsteps of country great Shunsuke Nakamura - who won six trophies during his time in Scotland.

Endorsed by Barca great
If there is one player who knows a thing or two about succeeding in Europe, it is former Barcelona captain Iniesta.
Iniesta - the most decorated Spanish footballer of all time thanks to 35 trophies at Camp Nou - was lured to Japanese club Vissel in 2018, the same year as team-mate Furuhashi.
Furuhashi tops the league's scoring charts this season with 15 in 21 appearances for third-placed Vissel, three more than ex-Brazil international Leandro Damiao (Kawasaki Frontale), Anderson Lopes (Consadole Sapporo) and Ado Onaiwu (F.Marinos).
He scored in his farewell appearance for Vissel on Saturday, the opening goal in the 1-1 draw with Cerezo Osaka.
Only Kawasaki's Yu Kobayashi (44) has scored more goals in J1 League than Furuhashi since his first appearance in the competition (August 5, 2018).
"To be honest, Kyogo absolutely has the talent to play in Europe," Iniesta said previously. "He's leading the J1's scoring chart, but it's not just that. He's got strong technique, and I believe he can succeed in Europe."
Since his J1 League debut three years ago, Furuhashi has been involved in 58 goals (42 goals and 16 assists), the most number in this period.
"I'm sure he's got scouts watching him already, but it's going to be tough for us because he scores a lot of goals," Iniesta added.
"It'll be tough but if he goes to Europe, I'll be incredibly happy for him, because for Japanese players it's a dream to play in Europe."
Ange turns to familiar face as Celtic rebuild
Furuhashi evidently left his mark on Postecoglou in Japan.
Coming up against Postecoglou's F.Marinos, Furuhashi scored three goals across all competitions.
On paper, Furuhashi seems to be the perfect fit for Postecoglou's high-octane, attacking style of football, having been involved in 106 shots (82 shots himself and 24 chances created) - the highest figure in J1 League this season.
Before his farewell appearance, Furuhashi had the highest non-penalty expected goals (10.9), best non-penalty xG per shot (0.14), most shots after a carry (30) and most shot involvements following a carry (37) in the competition in 2021.
"We are delighted to bring Kyogo Furuhashi to Celtic. He is a player of real quality and clearly someone I know well," Postecoglou said after a four-year deal was agreed on the back of the arrivals of Liam Shaw, Joey Dawson, Osaze Urhoghide, Liel Abada and Bosun Lawal.
Furuhashi - who has managed three goals in six appearances for Japan, with only two starts - will now test himself in Europe.
He has won the most points thanks to his goals and assists in the league this season (16 points).
Points won thanks to a player's goal is based on how many points a team would have accrued had a certain player not scored in that game at all. For example, a hat-trick in a 6-1 win gains no points, whereas one in a 1-1 draw gets one, two in a 2-1 win gets three, two in a 2-0 win gets two and so on.
"I think he will add something special to our squad and I am sure the way he plays will excite our supporters," Postecoglou said. "We look forward to welcoming him to Celtic."
