Pro Evolution Soccer 2011 (PES 2011, known as World Soccer: Winning Eleven 2011 in Asia) is an association football video game in the Pro Evolution Soccer series developed and published by Konami with production assistance from the Blue Sky Team. It was released in 2010-2011. The UEFA Champions League and UEFA Europa League are featured within the game, and for the first time in the series, UEFA Super Cup and CONMEBOL's Copa Libertadores are fully licensed.
With an exclusive deal with UEFA and CONMEBOL, the UEFA Champions League, the UEFA Europa League and, for the first time, the UEFA Super Cup and Copa Libertadores are fully licensed. The tournaments are integrated into the Master League mode, and for the first time in the Master League Online mode. UEFA Super Cup and UEFA Europa League, however, are only available on the PC, PS3, and Xbox 360 versions.
The game contains 79 national teams.
The Copa Santander Libertadores tournament is featured for the first time, such as its teams, which are fully licensed, but cannot be selected for play in any other game modes.
Like previous versions, there is also a separate two leagues with 18 empty teams (PES League and D2 League), each of which can be edited fully. Since its introduction, it has become very popular amongst the PES community, and as a result, they are usually made into the Bundesliga or another league of one's preference by patch makers. All the teams are entirely fictional.
