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?
Ronaldo vs Juve CL final 2017, simply because it’s the best player we’ve ever seen (in terms of prime/ peak) delivering again despite playing another world class team that knew exactly what he was going to do. I don’t think we’ll ever see a player at that level again.
