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. If a winner doesn't occur after the replay match the winner emerges by a flip of a coin.
