The very legendary referee of all time, with VAR eyes, is Pierluigi Collina. Most time, he officiates the finals of the World Cup and the Champions League final matches.
He speaks French, English Italian, and Spanish languages. What makes him extraordinary is that he studies the names of all players and the benched ones at heart. He calls players by their names before caution or carded. He had received several hands shakes from some players who lost their games.
At the age of 62, he runs throughout the game. What makes him extraordinary is his VAR eyes, which make him perfect at all times.
