Arsenal manager Unai Emery is a supporter of VAR.

The technology has been used in the Premier League for the first-time this season, with a number of coaches venting their grievances.

Speaking before Saturday's clash with Liverpool, Emery said: "For me, VAR is positive. It's coming to help us, to help the referees and to be fair in different circumstances in one game.

"After this, I think it's also right to think to not stop the intensity and the rhythm in the matches and not to stop for a lot of minutes. At the moment, sometimes it's going to be positive for us, sometimes it's going to be negative.

"But really, now, in my mind, it's positive for everybody, for every team and for the Premier League to help them. Sometimes it's helping us, sometimes it's not helping us, but it's fair."
