Former Arsenal boss Arsene Wenger insists the Premier League should persist with VAR.
Wenger has recently taken up a role with FIFA as chief of global football development, and gave his thoughts on the video technology being used to help match officials.
And he pinpointed the lack of referral by referees to their pitchside monitors as a crucial problem in the decision-making process.
"The referee needs a monitor to check if he was right or wrong," Wenger said. "For me, that is the most important worry."
He also feels more trust should be placed in those in charge.
Speaking at a general meeting of the International Football Association Board (IFAB) in Belfast, he added: "The referees on the field are there because they have the experience and they are confident."
