Following Newcastle United's 2-1 loss, at home to Wolverhampton Wanderers on Sunday, Rafael Benítez called for VAR to be "fast-tracked" after his side were denied a penalty and had DeAndre Yedlin sent off.
"If you see the incidents today, it's so obvious, the red card and the elbow in the face of Ayoze Perez. We need VAR right now," he added.
Benítez is not the only manager who has suffered from the lack of VAR, below are five more that have voiced their displeasure.
5. Everton Vs. Watford (December 2018)
Richarlison gave Everton the lead against his former club but during the build up to the goal, Theo Walcott was blatantly offside as he passed to Andre Gomes who cut the ball back to the Brazilian.
The game finished 2-2, Everton equalised in stoppage time, but Watford can feel hard done by as the Toffee's first goal should have been ruled out.
After the game, Watford manager, Javi Gracia said, "I prefer not to say anything about the referees. If VAR was ready the result would have been different."
The win would have sent the Hornets 8th in the league, on the same points as their opponents, but they are 12th.

4. Liverpool
Vs. Fulham (November 2018)
Fulham were bottom of the Premier League heading into this match and would need good fortune if they were going to take any points from Anfield - a ground where they had only won once at since 2012.
They thought they had taken the lead, through Aleksander Mitrovic, but his header was incorrectly disallowed for offside.
To make things worse, Mohamed Salah scored from the quickly taken free-kick, just 13 seconds after the away side had the ball in the Reds net.
Xherden Shaqiri added a second as Fulham struggled to get back into the game.
On Mitrovic's 'goal', Fulham's manager Slavisa Jokanovic said,"When I check the clip now it's Robinson who hasn't done a good enough job to squeeze up and my player is onside.
"In one moment, a crucial moment, instead of 1-0 up we're 1-0 down."
Jurgen Klopp admitted his side were “lucky” to have Mitrovic's 'goal' chalked off but that didn't help Jokanovic who was sacked three day later.
3. Crystal Palace Vs.
Arsenal (October 2018)
The Eagles were flying after a penalty from skipper Luka Milivojevic, on the stroke off half-time had give them the lead, but Arsenal fought back with a great free-kick from Granit Xhaka.
With the games finely poised, Alexandre Lacazette did his best Diego Maradona impression to glance the ball into the path of Pierre-Emerick Aubameyang who gave the visitors the lead.
The game ended 2-2, Milivojevic scored another penalty, but Palace saw this a two points dropped thanks to a refereeing error.
When asked if Arsenal's second goal should have been ruled out, Palace manager Roy Hodgson replied, "I think so, absolutely.
"Especially when, from my position on the bench, our players were complaining about the handball involved."
2. Liverpool
Vs. Manchester City (October 2018)
Both teams were unbeaten going into this game, level on 19 points, and they cancelled each other out in a tight contest.
These games are usually defined on fine margins and when Dejan Lovren bundled over Sergio Aguero in the penalty area, City should have been awarded a penalty however referee Martin Atkinson waved play on.
The Citizens did get a penalty later on, Riyad Mahrez skied it but it was the spot-kick that wasn't given that irritated Pep Guardiola.
"I would not like to speak about the referees, about the decisions," he said.
If Manchester City lose out on the league by two points, Guardiola may not be as diplomatic.
1. Southampton
Vs. Watford (November 2018)
The Saints were winless in seven games but were ahead, thanks to Manolo Gabbiadini, when Charlie Austin thought he double their lead.
However Jose Holebas equalised with nine minutes remaining and the game ended all square.
The fireworks went off after the match when Mark Hughes blamed his teams draw on a “bad mistake” from the match officials.
A furious Austin added, "It's ridiculous, they shouldn't be in the game. We scored a perfectly good goal make it 2-0, the game's done and dusted, we win the game."
