Pro Evolution Soccer 4 (known as World Soccer: Winning Eleven 8 in Japan and World Soccer: Winning Eleven 8 International in North America) is the fourth installment of Konami's Pro Evolution Soccer football simulation video game series. It's the first game of the series to appear on the original Xbox, with online gameplay. The cover features Arsenal striker Thierry Henry, AS Roma forward Francesco Totti, and world-renowned Italian referee Pierluigi Collina. It was the first game in the series to feature licensed leagues. Winning Eleven 8: Liveware Evolution marked the first game in the PES series to feature online play for the PlayStation 2, while Winning Eleven 8/Pro Evolution Soccer 4 does not feature it. Within online play, statistics and league points are stored on the server for each game played. PES 4 was succeeded by Pro Evolution Soccer 5, which was released in 2005.
