Celtic Reportedly Eye Rising Japanese Star Keita Kosugi Amid Competition from PSG and Atalanta
Celtic have been linked with a potential move for highly-rated Japanese youngster Keita Kosugi, who currently plays for Swedish side Djurgården. According to reports originating from Japan, the Hoops are one of several European clubs tracking the 19-year-old left-back, with heavyweights Paris Saint-Germain and Serie A’s Atalanta also believed to be in the race.
Kosugi’s profile aligns well with Celtic’s recent transfer strategy of identifying young, talented players with high potential resale value, particularly from the Japanese market. Since Ange Postecoglou’s tenure, Celtic have frequently dipped into the J-League and other pathways from Japan, bringing in talents like Kyogo Furuhashi, Reo Hatate, and Daizen Maeda. Kosugi could be next in line, though this time the competition for his signature appears significantly more intense.
The Japanese outlet Sponichi reports that Kosugi has attracted interest from several top European clubs following his breakthrough season in Sweden. The 19-year-old joined Djurgården in March 2024 after progressing through the ranks at Shonan Bellmare’s youth setup but never featured for the senior team in Japan. Despite that, he made an immediate impact after moving to Europe, breaking into Djurgården’s first team in May 2024 and quickly becoming a regular starter.
This season, Kosugi has featured prominently in the UEFA Europa Conference League, appearing in 11 matches and scoring twice — a notable return for a full-back. His performances helped the Swedish club reach the semi-finals of the competition, showcasing his ability to compete at a higher European level. He’s become known for his pace, tenacity in one-on-one duels, and tactical awareness on the flank, all qualities that would make him an asset in any league.
A Rising Star with Ambitions
Keita Kosugi was born on March 18, 2006, in Kamakura City, Kanagawa Prefecture, and began playing football with his local team, Nishi Kamakura SC. He went on to represent Shonan Bellmare’s U-15 and U-18 sides and has been part of various Japanese national youth squads. Kosugi even participated in the U-17 World Cup and has consistently been touted as a potential full international. There is growing speculation that he could earn his first senior national team call-up for the upcoming World Cup qualifiers in June.
Standing at 172cm and weighing 69kg, Kosugi is a naturally left-footed defender, praised for both his defensive resilience and his ability to contribute in attack. His career trajectory bears similarities to that of former Celtic full-back Jeremie Frimpong, who moved to Bayer Leverkusen in January 2021 after impressing in Scotland. Like Frimpong, Kosugi is seen as a player with the potential to thrive at the top level of European football.
Positional Questions at Celtic
While Celtic’s interest in Kosugi makes sense on paper, there are legitimate questions over where he would fit into the squad — particularly considering that Kieran Tierney is set to return to Parkhead this summer. Tierney, a product of the Celtic academy and former fan favourite, has reportedly agreed to rejoin the club after a spell at Arsenal and a loan stint with Real Sociedad.
With Tierney expected to slot straight into the starting XI at left-back, it’s unclear whether Kosugi would be brought in as a rotation option or with a view to developing into a long-term starter. Given Kosugi’s trajectory and reported ambitions — including a desire to win the Champions League — it’s unlikely he would be satisfied with a bit-part role at this stage in his career.
Still, Celtic do need depth at full-back, especially considering the physically demanding schedule that includes domestic and European fixtures. Injuries and form dips are common over a long season, and having someone like Kosugi available could prove invaluable.
One fan, commenting on Video Celts, speculated that Tierney might even be deployed as a centre-back to accommodate another left-back option, though that remains conjecture for now.
Celtic’s Changing Approach to Japanese Talent
During Ange Postecoglou’s first few transfer windows, Celtic went all-in on Japanese talent, at one point boasting six players from the country in their squad. However, not all those signings made a significant impact. Yosuke Ideguchi, Tomoki Iwata, and Yuki Kobayashi have struggled for minutes or consistency, with only a handful establishing themselves in the starting XI.
Kyogo Furuhashi was undoubtedly the standout success story, scoring prolifically and becoming a fan favourite before being sold to French side Rennes in January 2025 for a reported £10 million. Since then, the flow of Japanese arrivals has slowed, though interest clearly remains — especially if a player of Kosugi’s calibre becomes available.
Competition and the Road Ahead
The biggest hurdle for Celtic in securing Kosugi’s signature will be the level of competition. Paris Saint-Germain and Atalanta are both significantly larger clubs with deeper pockets and greater pulling power. PSG, fresh off winning their fourth straight Ligue 1 title and domestic cup, are eyeing a Champions League treble and could offer Kosugi both financial incentives and the opportunity to play on the biggest stage in club football.
Atalanta, known for developing young players in Serie A, also present an attractive option. Kosugi’s camp will no doubt weigh all the offers carefully before making a decision, with his dream of winning the Champions League likely to influence the outcome.
For Celtic, the key will be to present a compelling project — one where he can develop, get regular playing time, and use the club as a springboard to a bigger league in a few years, just as Frimpong did. With a Champions League play-off looming in late August, manager Brendan Rodgers and the club’s recruitment team will be keen to get their summer business wrapped up early.
Pre-season training is scheduled to begin shortly, with Celtic set to face Cork City in their first friendly on July 8. Any new recruits will ideally be through the door well in advance to integrate into the squad and tactical setup.
Whether Kosugi ends up in Glasgow remains to be seen, but his name is certainly one to watch as the summer transfer window heats up.
