Distinguish original rank from inherited position
Article 19 gives the league-phase top four a home return leg in the quarterfinals and the top two the same advantage in the semifinals. It then explicitly says the team eliminating a seed takes over that seeding position, rather than rankings being recalculated after every round.
The practical consequence is that a surviving team’s original league position does not, by itself, answer where a later return leg belongs. Retain both the original league rank and the position occupied in the knockout bracket. They describe different information after an upset.
The bracket path determines the comparison
For a hypothetical upset, record which seeded position the winning side has taken over and trace that route to the next round. Do not sort all surviving clubs into a fresh league-table list and assume that list reproduces the published draw. That would replace UEFA’s specified mechanism with a different one.
The regulation also describes paired league ranks and draws into predetermined positions for the earlier knockout stages. A draw graphic can therefore contain constraints that are not apparent from a list of the clubs still involved. Use the actual official bracket when selecting the next match rather than predicting opponents from reputation.
A nominal home team in the final is another concept
Article 19 separately assigns the final’s nominal home team for administrative purposes according to the bracket’s silver side. That label is not the same thing as staging the final at the club’s usual stadium. Preserve the announced venue as a separate field in a viewing reminder.
The primary 2026/27 regulation was checked on 4 November 2026. It also reserves authority to adapt draw conditions for relevant constraints. Final dated fixtures remain the reference for a real match; this explanation does not invent the future knockout participants, venue changes or local kickoff times.
