Just like in the League, every Top Eleven manager participates in the Cup, regardless of the results from the previous season. The Cup starts at the first season day and it represents a play-off competition. You play two matches against opponents from various levels and after two matches the winner of the clash is decided by the “Away Goals Rule” or by penalty kicks. The winner advances further into the Cup, while the loser is knocked out of the Cup.
The finals are played on a neutral venue, which is usually the largest stadium on the server.
Participants: 128
Matches: from 2 to 13
Prize: Depends on the level of the highest level opponent in the competition
