A month has passed since the end of the World Cup in Russia, hailed by many as one of the best ever. Gab Marcotti caught up with Pierluigi Collina, chairman of FIFA's referees committee and the man in the middle for the 2002 final between Brazil and Germany, to talk about officiating, video assistant referees (VAR) and the future.
