Celtic fans would welcome Kyogo Furuhashi back despite his previous departure. He was a crucial player for Celtic, scoring important goals in cup finals and derbies. Although he left because he wanted to, the club made a good business decision with a £10m fee. However, there are concerns about his shoulder injury and potential surgery. EPL club Bournemouth is also believed to be interested.

Kyogo Furuhashi's move to Rennes has not been successful as he is considered fourth or fifth-choice striker. Rennes plans to spend on new attackers, making Kyogo's return to Celtic plausible. There is speculation that Celtic could re-sign him for about £3 million. His return could help him regain form and potentially secure a place in Japan's squad for the World Cup.
