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?
Maybe not as high as some others in this list due the the differences of the teams on paper, but I remember Ronaldo against Wolfsburg in the second leg of the CL being one of those kind of moments. Adding to that, RM lost 2-0 in the first leg, so there was that pressure to perform.
