UEFA removed the away-goals tie rule from its club competitions from the 2021/22 qualifying phases onward. In a current two-legged tie, an away goal does not receive a special tie-breaking weight. Add the goals normally, then use the competition's current continuation procedure if the aggregate remains level.

Avoid the phrase count double
Even historically, the away-goals rule was a way to separate a tied aggregate, not an ordinary arithmetic instruction to double every away goal on the main scoreboard. That old shorthand is especially unhelpful now. For a current tie, one goal adds one to the club's aggregate total. If an old commentary clip says an away goal changes the route, check the season before treating it as a current rule. Historical footage can be accurate for its own event and wrong as present-day advice.
Use a simple aggregate example
Suppose one club wins the first leg two-one and loses the second one-nil. Each club has scored twice across the tie. Under the current knockout framework, the location of those goals does not itself identify a winner. The match proceeds under the applicable extra-time and penalty provisions. This is an illustrative calculation, not a claim about a particular fixture. Keeping the example named by club rather than by home and away avoids reversing the totals between legs.
Do not confuse a table criterion with a knockout rule
UEFA's league-phase regulations can use detailed criteria to separate clubs level on points. A reference to away goals in a table article does not restore the old knockout tie rule. Read the article title and competition stage before applying a phrase. The league phase, a two-legged knockout tie and a single-match final are different structures. Search snippets often remove those headings, which is one reason the full official regulation is a better source for a disputed result.
Check the actual edition when watching a replay
A match from before the change can have a conclusion that seems surprising under today's procedure. Do not reinterpret the old result through a later rule. Keep the year with the clip and use the rule that governed that event. For current viewing, record the aggregate and the next possible procedure before the second leg. That makes a late goal's consequence understandable without relying on a slogan that belongs to an earlier era.
Useful answers
Do away goals break a level aggregate in a current UEFA club tie?
No. Use the current competition’s extra-time and penalty procedure when the aggregate is level under the relevant rules.
Can an older UEFA replay legitimately use the former rule?
Yes. The event followed the rules in force at that time. The change does not rewrite historical results.
