The use of the Video Assisted Referee (VAR) in the Premier League has been vindicated despite several controversial decisions and criticism from fans and pundits, according to the system's chief Neil Swarbrick.
Speaking to the media on Monday after the latest round of matches in which Sheffield United had a goal disallowed for offside against Tottenham and Manchester City were denied a penalty for handball against Liverpool, Swarbrick defended the technology.
"We are in the infancy with VAR, 12 match weeks into the Premier League season, and you need to give us time to operate and utilise it," he told Sky Sports.
"It is working as we wanted. It's taken quite a few years for other competitions or sports - the likes of cricket and rugby union - to get to where they are today regarding technology. It doesn't happen overnight."
VAR was introduced in the Premier League this season after trials in the League Cup and FA Cup.
"I'd give us around about seven-ish. We have more decisions correct with VAR than without it," Swarbrick said when the BBC asked how he would rate the use of VAR on a scale of one to 10.
"If the mark now is seven - early days - in two years' time I'm hoping for maybe an eight and a half or nine.
"We are open to evolving with this - it's not a case of we're not budging. We will listen to feedback and where we can improve things, we will do."
Some pundits were less enthralled with the system which has also infuriated fans around the world, mostly for decision-making delays which take up to several minutes.
Chris Sutton, who won the Premier League with Blackburn Rovers in 1994/95, was one of the system's harshest critics.
"Seven out of 10? Did he really say that with a straight face? Come on, are you serious?" Sutton told the BBC.
"There have been so many high-profile, horrific mistakes. They've got too much wrong. I wanted VAR to work, I backed VAR, but they are making such a mess of it."
Former England goalkeeper Paul Robinson also pulled no punches in criticising VAR.
"It's been a complete mess from day one and it's caused more problems than it's worth."
