Buenos Aires and South Korea's Jeonbuk Hyundai, while some established Asian powerhouses such as Uzbek Cotton Farmers and Saudi Arabian Hilal were eliminated. The current pattern of the top eight is five West Asian teams and three East Asian teams. Although the draw will be a mixed draw, the quarter-finals will still be conducted in the same region of East Asia or West Asia. Except for one game, it must be within West Asia. In addition to the intermittent games, the other three East Asian teams will have to compete with the West Asian teams. Since Dalian Shide has been eliminated, Shanghai Shenhua will challenge the West Asian wolves alone.
