The UEFA Champions League knockout stage is the final part of the competition, featuring the top eight teams from the group stage. Here’s how it works:

The 16 teams that finish third in their groups join the 16 group winners and runners-up to make up the 32-team knockout stage.
The draw for the round of 16 takes place after the completion of the group stage, with teams seeded based on their group-stage performance.
Teams are placed into one of four pots, based on their UEFA club coefficient ranking. The top four seeds are then allocated to the top four pots, and the remaining teams are assigned to the other two pots.
The round of 16 is a single-elimination tie, with the winner advancing to the quarter-finals and the loser being eliminated.
Quarter-final ties are also single-elimination, with winners going on to the semi-finals and losers exiting the competition.
The semi-final draw also takes place after the completion of the quarter-finals, with teams again seeded based on their performance.
Semi-final ties are played over two legs, with the aggregate score determining the winner. The winners then advance to the final, which is played at a neutral venue.
