their starting rounds. Notes Format Each tie is played over two legs, with each team playing one leg at home. The team that scores more goals on aggregate over the two legs advance to the next round. If the aggregate score is level, the away goals rule is applied, i.e. the team that scores more goals away from home over the two legs advances. If away goals are also equal, then extra time is played. The away goals rule is again applied after extra time, i.e. if there are goals scored during extra time and the aggregate score is still level, the visiting team advances by virtue of more away goals scored. If no goals are scored during extra time, the tie is decided by penalty shoot-out. For the Champions Path, in the draws for each round, teams (whose identity is not known at the time of the draws) are divided into seeded and unseeded pots, which may contain different numbers of teams, based on the following principles: In the second qualifying round draw, 15 of the 16 losers of the Champions League first qualifying round (excluding 1 team which receives a bye to the third qualifying round as decided by an additional draw held after the Champions League first qualifying round draw) are seeded, and the three losers of the Champions League preliminary round are unseeded. In the third qualifying round draw, the ten losers of the Champions League second qualifying round are seeded, and the loser of the first qualifying round which receives a bye (whose identity is known at the time of the draw) and the nine winners of the second qualifying round are unseeded. In the play-off round draw, the six losers of the Champions League third qualifying round are seeded, and the ten winners of the third qualifying round are unseeded. In the beginning of the draws, a seeded team is drawn against an unseeded team, with the order of legs in each tie decided by draw, until one of the pots is empty. Afterwards, the remaining teams from the non-empty pot are drawn against each other, with the order of legs in each tie decided by draw. For the Main Path, in the draws for each round, teams are seeded based on their UEFA club coefficients at the beginning of the season, with the teams divided into seeded and unseeded pots containing the same
