Speaking to the media after the match, Emery said: “VAR is positive but at the moment it is not working well.
“I think we deserved to win this evening. Only I can be disappointed about not controlling the match better.
“I think VAR is very important for the referees because their mistakes are very important.
“When it’s used in the right way but now we haven’t checked a lot of things to not change the pace of the match.

“The next step is a monitor on the touchline to check because VAR is to help referees.”
