UEFA trialled a new penalty shootout system at the Euro U17 Championship similar to tennis’ tiebreak format.
The governing body have tested a format where teams no longer alternate penalties, but each have two in a row after the initial spot kick.
And Fifa have followed suit by introducing the same system for the Under-20 World Cup.
Known as ABBA, the system is designed to prevent the team that goes second from being put at the psychological disadvantage of always having to play catch-up.

Currently penalty shootouts see team A and team B take five penalties each in an alternating pattern with sudden death used after that if the scores are level.
But the new system involves team A taking the first penalty, team B the second and third, team A the fourth and fifth and so on until each team had taken five.
The sequence would continue if the shootout then goes to sudden death.
Uefa said: “The hypothesis is that the player taking the second kick in the pair is under greater mental pressure.”
“If the opposition’s first penalty in the pair has been successful, a miss by the second penalty-taker in the pair could mean the immediate loss of a match for his team, especially from the fourth pair of penalties onwards.”
As with the existing system, the referee will toss a coin to decide at which end of the pitch the shootout takes place.
The referee will then toss the coin for a second time and winners can decide whether to take the first or second kick.
