Each tie was played over
two legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, the
away goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced. If away goals were also equal, then
extra time was not played and the winners were decided by a
penalty shoot-out. ==Teams==
