Eight teams were drawn for the preliminary round while the other four seeded teams received a
bye for that round. The eight teams will play against one another in a single-legged knockout basis. Winners of this round will progress and advance to the
quarter-finals. Thereafter, matches are played in
two legs with the exception of the one-match final. For any match in the knockout stage, a draw after 90 minutes of regulation time is followed by two 15 minute periods of
extra time to determine a winner. If the teams are still tied, a
penalty shoot-out is held to determine a winner. ==Bracket==
