Important, the „level“ off the player isn‘t relevant. If a role Player played like a god in a Game he qualifies here.
We also talk about 1 game.
Basically we are looking for the greatest 10/10 Performance off all time.
Can be a Goalkeeper that made 26 Saves, can be a midfielder that made 100% off his passes and 4 assists etc, you get it.
This Question can also be labeled to „most dominant Performance in Football off all time.“
What is you‘re call?
Maradona against nst Brazil in 1990 comes to mind. Or his entire 1986 world cup, especially the quarter and semi finals.
Zidane against the nst Brazil in 2006 was great too.
