Pick up a match and turn
just one episode such as:
1)a post hit
2)a goal not conceded/given
3)a penalty not conceded/given
etc
into:
1)a goal
2)a goal given/not conceded
3)a penalty given/not conceded
etc
the accident must be real, not invented and based on factual proof, like for instance Youtube videos of that match and must be able to switch the outcome of that match
note:to make things easier the away goal rule works since the very first season of the competition as well penalty shoot out
I begin:
1955-56
in the semifinal Real Madrid-Partizan Beograd the Yugos mark goal in the first half and the number 4 Lesmes doesn't save
you can see this at 1'41''

so the semi in ATL ends Real-Partizan=4-1 instead of 4-0
in the return Partizan beats Real 3-0, just like in OTL of course and passes to the final where they will beat Stade de Reims
consequences for the next season:
just one Spanish team in Champions League, i.e. the National champions of La Liga Athletic Bilbao
and two Yugoslavian clubs, the Euro champions Partizan and Red Star, the champions of Yugoslavia
Partizan will be scheduled as Real Madrid, therefore meeting Rapid Wien, Nice etc
while Red Star and Bilbao will be scheduled as in the OTL
