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?
For me, it was Messi against Arsenal in 2010. I can remember watching the match with my Dad as a neutral, and he felt Messi was overhyped, and there was constant talk about how he “didnt play well against English teams” in the media. Up steps the GOAT. 4 goals. No more doubts.
