Video assistant referee causes controversy in the premier league but how are decisions made and are they correct

We take a look at the major incidents and explain the process in terms of VAR protocol and the laws of the game after each weekend.

The VAR decisions affected every club.

A jump to: Bournemouth, Spurs, Wolves, Man United, Palace, and West Ham.

The return of Howard Webb

It probably wouldn't have changed much if Howard Webb had mapped out the first 20 games of his tenure as the new head of the referees. The two rounds of games played over Christmas went by without a hitch.

Even though he has held one get-together with all the referees in the league, his mere presence isn't going to fix all the problems.

One of the aims of the first day of the new season was to improve the transparency of decision making, something that may take some time to come to fruition. Andy Madley was the referee who turned down the VAR review to prevent a goal for the Cottagers. There were six incorrect VAR interventions in the first part of the season, all of which involved a referee being sent to the monitor and changing their own decision.

The VARs should back their own judgement to cut down on missed interventions, rather than relying too much on what the referee has seen, according to instructions given by the man in charge of English football. It's early days, but a perceived lack of confidence on the pitch or in the VAR room had been an issue in the premier league

Chelsea 2-0 Bournemouth

There is a chance of a penalty for Smith pulling on Pulisic.

Christian Pulisic broke into the area in the 12th minute and shot wide, but fell as he did. The United States star tried to get a penalty for a pull by the Bournemouth player.

There was no penalty.

A lot of supporters want this to be a penalty. Smith held the shirt, but that doesn't mean he committed a foul. The question is if it was long enough to prevent him from taking the shot.

The referee didn't think there was enough in it, and the VAR decided there wasn't a clear error. It didn't help his case that he appeared to ground after the pull.

It could have been a spot kick if Smith had taken the risk. There is no chance that the VAR will overturn the referee's decision.

The impact was judged on the borderline.

At the start of the season, we saw an example of shirt pulling when Matheus Nunes held on to the shirt of Sean Longstaff, who was on the other side of the field. The referee allowed play to continue and the VAR didn't advise a review.

The independent five-man panel ruled that the Nunes- Longstaff incident was a clear and obvious error and that the VAR should have been involved. With Longstaff having his shirt pulled away from his body, the panel might agree with Coote for the game.

Brentford 2-2 Tottenham Hotspur

Penalties could be on Kane.

In the 51st minute, Harry Kane tried to meet a cross from Ivan Perisic but went to ground. The England captain wanted a penalty for holding, but the referee didn't want to start the game.

There was no penalty.

Kane was going to ask the question after seeing a number of penalties awarded for this kind of grappling offence.

The referee for this game the day before he was on VAR for Bournemouth was the same one as Smith on Pulisic.

At one point, Mee has his arm around Kane as the two players come together. The VAR will have been interested in the quick release of Mee. There was a degree of holding from both players, not just the case of Mee blocking the run from Kane.

Stuart Attwell thought there wasn't enough in it for a review. It's not likely that an incident like this will result in a penalty.

Wolverhampton Wanderers 0-1 Manchester United

There is a chance that Rashford could get a penalty when he scores.

There was a chance the ball came off his arm before it went into the goal.

The goal was ruled not to be a goal.

A classic disallowed goal of the VAR era is included in the VAR review. It was an automatic decision to disallow the goal because the ball hit his arm after the initial save by the goalkeeper.

It would be hard for Robert Jones to pick it up in real time.

Crystal Palace 0-3 Fulham

There is a chance of a penalty before Ream goal.

Tim Ream gave the Cottagers a 2-0 lead at Selhurst Park in the 71st minute, but the USMNT defender scored on the rebound. Mike Dean initiated a review to overturn the goal.

The goal stands.

This should never have been used for a VAR review.

If a player deliberately plays the ball with their head and it hits their own arm, it shouldn't be a handball even if the arm is away from the body. Andy Madley was sent to the monitor by Dean because of the handball.

There was no intent on the part of the man. Madley made a great decision to stick with his original decision. The referee avoided an incorrect VAR intervention when he was at the monitor, perhaps because he heard the words "Confidence in your own decisions" from the speaker.

Brighton & Hove Albion 2-4 Arsenal

There's a chance that Mitoma will score before it happens.

There was a VAR review on the way in which the Seagulls thought they had made it 4-3 through Kaoru.

The VAR decision was that the goal was not scored.

VAR review is the kind of VAR fans dislike, but which creeps up on them without you knowing.

A throw-in went to Evan Ferguson, who tried to control the ball, but it dropped down, and that's when Mitoma ran over and scored.

The boot of his trailing leg was slightly ahead of the last defender as he ran back from an insturment position, having offered himself to receive the throw at the time the ball touched Ferguson.

The position of the attacker relative to the second-last defensive player is more important than the direction of the ball.

The right decision was made by the VAR.

The VAR confirmed a correct onside decision by the assistant after the Japan international had a tight offside call. This was a very close call and only onside by the level of tolerance applied to VAR in the league.

West Ham United 0-2 Brentford

There is a penalty review on the spot.

The position of the foul needs to be checked by the VAR.

The penalty was turned into a free kick.

The VAR has to judge a penalty on where the first contact takes place and not where the attacking player will end up.

The ref was told by the VAR that it was outside the box.

Manchester United 3-0 Nottingham Forest

Boly was ruled to be in an ineligible position when he scored.

In the 40th minute, a cross came in and the ball came off Ryan Yates, but there was a double VAR review that ruled out the goal.

The goal was not allowed by the VAR.

The review took a long time as Boly was not the goal scorer.

Andy Madley applied the review in chronological order. It would be better to review the offence by the goal scorer and the rest of the attack phase. Madley might have been unaware that Boly was the scorer.

Madley looked at various angles to see if the ball hit Yates' arm, but replays were not conclusive, so he headed the ball onto his own arm.

Yates didn't score the goal with the ball touching Boly before going into the net, but it was obvious that he did. The factual decision against the goal scorer could have been checked by Madley.

Arsenal 3-1 West Ham United

The penalty was given for Foul by Saliba on Bowen.

He stumbled to the ground in the 24th minute. The penalty was awarded for a trip by William Saliba.

The penalty is standing.

The forward lost his balance because of contact between his legs.

The referee's decision to award a spot kick wouldn't be considered clearly and obviously wrong by the VAR, but the VAR wouldn't advise a penalty if the referee hadn't given one.

The penalty was given by the referee.

At the end of the first half, Oliver awarded a penalty when he thought the ball had hit the arm of a player.

There was no penalty.

Fans thought VAR would be used for howlers that would have been clear injustice when it first came in.

There is a quick and easy VAR decision.
