The head of the A-League's referees is defending the standard of officiating in this year's competition.
The Wellington Phoenix have criticised the refereeing in the league following the club's loss to the Brisbane Roar.
Director of referees Mark Shield says while there's always room for improvement, the officiating has been very good this year.
Shield says they have someone monitoring every single refereeing decision and 93 per cent of their decisions have been correct.
Shield says they're currently reviewing the Phoenix-Roar match and he's open to talk to the Phoenix once it's completed.
