LONDON (Reuters) - The use of video assistant referee (FAR) technology has not prevented four wrong decisions in Premier League matches this season, the president of the Association of Professional Referees (MCA) has admitted.
Riley, who heads the association that oversees the application of video judgment in England, said the technology represented "value added for sport" but added that there were facts in which the referee should have reversed his decision.
"If you look at the matches of the four rounds, 227 incidents have been examined. Of these, six decisions have been changed. We think 10 decisions should have been changed in total," Riley told Sky Sports on Thursday.
"This gives you a measure of where video assistants can help and add value to the game, but it also confirms that it is up to the referees to manage the Premier League matches off the pitch at the end."
The rules of the video adjudication rule state that the technique should only be used to change a decision if the meeting judgment makes a clear and obvious mistake.
Riley said the technique should have been used to give defending champions Manchester City a 3-1 victory over Bournemouth and a West Ham United 2-0 home win over Norwich City.
He added that Fabian Cher's goal for Newcastle United in a 1-1 draw with Watford should not have been counted because of a handball before, while Leicester City's Yuri Tillmans should have been sent off in a 3-1 win over Bournemouth.
The Premier League has joined the first division in Germany, Spain and Italy in assisting video refereeing since the start of the season and has played a crucial role in the first four rounds.
