The Italian with the distinctive look and refereeing style has taken charge of the biggest matches on the planet. He is perhaps the most widely known referee in the world today.
Collina's relationship with players on the field was almost without comparison. He kept things in order with a calm smile or a stern glance and the players say they enjoyed his presence.
He once said, "I think this is one of the most important things because if you have good relations, with all the actors in a match including the coaches, it's possible to have a better match - the players can do their job, and the referee can control the match better".
After his retirement in August 2005 he concentrated on his own business as a financial advisor. Pierluigi Collina is still involved in football as non-paid consultant to the Italian Football Referees Association (AIA), and is a member of the UEFA Referees' Committee. He is still regarded as one of the best referees in the world.
