3. Jim Fleming (Scotland)
Incredibly spent 18 seasons as an international referee and his World Cup CV takes in four tournaments between 1987-1999 (he and Derek Bevan are the only two referees to achieve this feat).
After a low-key start in ‘87 Fleming refereed England-New Zealand four years later plus the Ireland-Australia quarter-finals and Australia-New Zealand in the last four.
His big game in ‘95 was the South Africa-Samoa quarter-final while he was the man in the middle for the South Africa-England last eight clash in ‘99 as well as the France-New Zealand semi-final.
