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?
Purely in terms of what I have personally seen it would have to be;
Tim Krul for Newcastle in the 2013-14 season.
