VAR could be introduced from Champions League round of 16

The Video Assistant Referee is there to keep a check on the decisions that are made by the referee or make the referee aware if something has happened without his notice.

Numerous video feeds from different angles are watched by the VAR team so that nothing escapes their eye.

The referee can himself call for a video review or the VAR can directly consult him.

Although VAR was introduced in several leagues throughout Europe, and at the World Cup, UEFA, so far, had refrained from bringing it in the UCL.

UEFA president Aleksander Ceferin had said, " It is much more problematic than it looks. The plan is to do it for next season but let's see what happens."

Reports now suggest that VAR might be in place this season itself.

Diego Costa's goal against Portugal in the group stages stood even after Portugal appealed that he had fouled Pepe.

Griezmann would have been denied a penalty if VAR had not intervened in France's match against Australia.

In Egypt's match against hosts Russia, Salah was given a freekick at the edge of the box, but VAR determined that it was a clear penalty.

During Cristiano Ronaldo's first Champions League match with Juventus this season, the Portuguese legend was wrongly sent off when he touched the head of a Valencia player, and the decision, severely disputed in the media, could have been overturned by VAR.

Even Manchester City forward Raheem Sterling was awarded an undeserved penalty where replay showed that he had tripped on the pitch.
