The video assistant referee, better known as VAR, has become a big discussion in soccer for the better part of the last five years. Almost every major league and tournament has it already or is soon to be accepting and implementing VAR. The 2019 FIFA Women's World Cup in France will be no different.

Although many men's leagues uses VAR, no domestic or international women's competition uses VAR currently, so it will be new to almost everyone involved in the 2019 Women's World Cup.

This is not the first World Cup that VAR has been used in, so players, coaches and fans should be prepared on how the technology will help and how much time it will add to games. 

Here's a look at how VAR works: 

VAR was first introduced at the 2018 World Cup in Russia. The video system can review four types of calls: goals, penalties, straight red cards and mistaken identity. Throughout the course of the 2018 World Cup, 455 incidents were checked (7.1 per game) and there was 20 VAR reviews, averaging about one review every 3.2 matches. Seventeen of those calls were changed.

FIFA statistics showed that VAR helped referees call the game at an almost perfect rate. With VAR, referees made the correct call 99.35 percent of the time, compared to 95.6 percent without VAR. 

There was a concern that VAR will slow down the game too much with long breaks, but that is a fallacy. The average time of the reviews was 81.9 seconds. 

VAR had a big impact on penalty kicks, as it is one of the hardest calls to make in a split-second. Nine penalty kicks were awarded from VAR in the 2018 men's tournament, which had the most penalty kicks of all time. There were 29 penalties taken, up from 13 kicks from the penalty spot in Brazil 2014.

Any player that signals the hand gesture for VAR is automatically handed a yellow card.

The first game of the Women's World Cup will be on June 7 between the host country France and Korea Republic. You can stream every match via fuboTV (Try for free).
