JEF United Ichihara Chiba
In October 2008, Gamba for the first time in their history, reached the final of the AFC Champions League after defeating fellow Japanese league rivals Urawa Red Diamonds 4–2 on aggregate after a 1–1 draw at home in the first leg, Gamba registered one of the most historic comebacks in Champions League history when they came back from being behind 1–0 before half time to win 1–3 with all goals scored in the second half at Saitama. Gamba Osaka went on to win the 2008 AFC Champions League title after winning 5–0 on aggregate against the giant-killing Australian club Adelaide United in the Final. They became the fifth Japanese club to win the maximum Asian title, after Urawa, Júbilo Iwata, then-company-affiliated Yomiuri (now Tokyo Verdy), and Furukawa Electric (now JEF United Ichihara Chiba).
