Since its introduction to the Premier League in the 2019/2020, VAR has frustrated football fans by deeming armpits offside and transforming games with soft, or sometimes downright bizarre penalty calls.
Many teething problems with this new mode of officiating have been resolved, but questions over the consistency of rulings remain.
Leeds' FA Cup third round tie with West Ham United sprung fresh controversy as a lengthy VAR review did not overturn Manuel Lanzini's opening goal.
Jarrod Bowen appeared to be offside before stepping into Illan Meslier's path and preventing him from collecting the ball, but Stockley Park approved the Irons' 34th-minute lead.
West Ham's advantage forced Leeds to chase the game and, with Whites players committed forward to an injury-time corner, Bowen doubled the Irons' lead following a fast break by Michail Antonio to seal his team's passage into the fourth round.
Leeds head coach Marcelo Bielsa, though, opted not to speak out against the decision in his post-match press conference.
"It's a decision I prefer to accept what the referee's say, not because I don't have an opinion, I think it's a collaboration us coaches should make, to accept the decisions to the referees even if they jeopardise us," Bielsa said..
"If not we enter terrain where we can't offer what we want to offer, which is good football.
"There is a lot of arguments to say that the position I'm taking is incorrect, I consider them and I revise them but adding and subtracting I think the decision to accept their decisions helps their job and the spectacle.
"There are some conclusions that say the ones that demand the least would seem that it facilitates for the referee in case of doubts that they go towards the one that complains the least.
"I think the argument I'm offering is superior."
Here are 16 occasions when the spectacle of VAR put Whites fans on the edge of their seats:
7. Lookman winner chalked off at Elland Road, November 2021
Ademola Lookman appeared to have completed the Foxes’ turnaround at Elland Road as he scored a back-post tap-in to put Leicester 2-1 ahead. A VAR review found he had been in an offside position when Jamie Vardy flicked the ball towards him, so the goal was disallowed and the game ended honours even. Photo: Michael Regan
8. Bamford offside against Crystal Palace, November 2020
Patrick Bamford linked up with Mateusz Klich to equalise at Selhurst Park, but VAR remarkably deemed his arm, outstretched to show his teammate where his run was heading, was offside. The goal was chalked off and the Whites lost 4-1. Photo: Glyn Kirk
9. Saïss’ goal disallowed for offside, October 2020
Romain Saïss looked to have put his side ahead before VAR found the provider Daniel Podence to have been offside in the buildup. It didn’t stop Wolves, though, as Nuno Espírito Santo’s side claimed a 1-0 victory thanks to a 70th-minute strike by Raúl Jiménez. Photo: Martin Rickett
10. Antonio fouls Meslier to cancel Souček’s winner, September 2021
Tomáš Souček poked the ball home in a six-yard box scramble to give West Ham the lead after trailing at Elland Road, but Michail Antonio was later found to have fouled Illan Meslier at the corner, so the goal was chalked off. The striker made up for it though, scoring a 90th minute winner for his side as they came from behind to win 2-1. Photo: Stu Forster
11. Ayling goal disallowed, March 2021
Luke Ayling treated Leeds United fans to his full mane of hair when celebrating what he thought was his first Premier League goal against Fulham at Craven Cottage. VAR’s ruling was cruelly tight, and Tyler Roberts’ offside position denied Ayling his glory. Photo: Matt Dunham
12. Bamford offside at Wolves, February 2021
With Wolves leading by a freak goal - rebounding off Illan Meslier’s head into the net - Bamford was relieved to grab a late equaliser at Molineux, only for the VAR to confirm the on-field decision of a marginal offside. The striker tweeted: “Gutted for the lads tonight, robbed of a point but at least it’s ‘mAkInG tHe GaMe BeTtEr’.” Photo: Catherine Ivill
