Knockout phase

In the knockout phase, teams play against each other over a single match. If the match ends up as a draw, extra time will be played and if the match remains a draw a replay match is set at the home of the guest team which the extra time rule stands as well. That procedure will be repeated until a winner occurs. The mechanism of the draws for each round is as follows: The seeded teams are drawn against the unseeded teams.
