I have been following Refereeing World during the tournament but have not yet discovered the final two referee appointments for Third/Fourth place game and the Final.
My record of officiating in the Knockout Phase (14 games played) defined by percentage of ball in play time is:
Games completed in normal time (n=9) (colour code of dots is for fouls awarded):
Games completed after extra time (n=5) (colour code of dots is for fouls awarded):
Based on the data from this tournament, if the choice of referee was independent of the politics of appointment, my choice for World Cup Final referee is Bjorn Kuipers (Netherlands). Three of the four games he has refereed exceeded 63% ball in play . The Sweden v England Game was 59%.
