UEFA president Aleksander Ceferin has waded into the recent VAR debate, admitting that there is a long way to go to realize desired results.
The technology has become under serious scrutiny, especially in the English Premier League, following controversial decisions.
The Video Assistant Referee system was meant to reduce the number of errors in officiating, but it is rasing for more questions instead of providing more of answers to onfield situations.
"It is a mess," Ceferin was quoted saying by the Daily Mirror. "I don't think the tolerance of one or two centimeters for offside, for example, is enough,"
"We will propose a change to the IFAB. And also for our referees."
Caferin admitted that the will need to improve on various officiating points in future, but clarified that there was no turning back.
"We don't have many interventions in Uefa competitions because our chief refereeing officer, Roberto Rosetti, said to the VAR: It has to be a clear and obvious mistake," he added.
"I'm not a fan. I was very skeptical and I can say that I don't like the outcome. "Unfortunately, there's no way back anymore,"
Premier League clubs have voiced their frustrations over the VAR, resulting in a meeting in mid-November to discuss how best to improve the usage.
