Controversy erupted after the decision to chalk off Gabriel Jesus' second-half goal.

With VAR making its debut in the Premier League this season, the technology was bound to make its presence known at some point. This moment just happened to be the second game of the season.

That fixture was Man City’s clash with West Ham. This early Saturday kick-off saw the reigning champions begin their title defense at the Olympic Stadium, with this match being the first-ever English top-flight game to witness a VAR referral.

The Citizens broke the deadlock in the first half thanks to Gabriel Jesus before De Bruyne and Sterling combined to double their lead. The Brazilian forward thought he completed his brace when he found the back of the net for a second time, burying the ball into an empty net after a lovely build-up, but Video Assistant Referee had other plans.

The goal immediately underwent a VAR check before Mike Dean overturned it after Sterling was deemed to be offside when setting up Jesus. However, controversy soon erupted as it was only the Englishman’s arm that appeared to have been offside.

Only when a part of the player’s body that he can score with is offside can the player be flagged but the goal was chalked off nonetheless. This led to many criticizing VAR as still being faulty.

Others were keen on trolling Mike Dean, a referee who is popular on social media for all the wrong reasons. Check out the best tweets below.
