Anthony's offside 'disappointment'
Burnley's first heartbreak came in the 78th minute when Zian Flemming thought he had bundled them into a 4-3 lead, but the offside flag quickly followed.
Jaidon Anthony, scorer of Burnley's second goal, was offside by the width of his shoulder, something he described as "disappointing".
"I've seen the one where I'm offside. It's my shoulder, I think," Anthony said.
"I'm sure if I scored with that part of my body, it wouldn't have been a goal. It's disappointing."
Scott Parker was philosophical when talking about the "fine margins of technology".
He said: "It was heartbreaking for us, really, because we deserved that.
"VAR and the fine margins of technology to the inch of a sleeve, calling something offside is the game of football we live in now. So we accept that. That's the way it is."
But could this rule soon change?
The Canadian Premier League has put itself forward to trial a proposal by Arsene Wenger, Fifa's head of global football development since 2019, that there should be a complete gap between the attacker and the second-to-last opposition player - effectively the last defender, given the goalkeeper's usual positioning.
Shearer on 'messed up' handball rule
Fast forward to the 99th minute and with Burnley now trailing 4-3, Turf Moor was sent into raptures as Ashley Barnes thought he had equalised with the final kick of the game.
Fans were left waiting for five minutes as VAR attempted to determine whether the ball struck the arm of Barnes in the build-up to his goal.
The VAR decision of 'accidental handball' led to Alan Shearer describing the rule as "messed up in every single way".
"I just hate the handball rule. Whether it's today's decision at Burnley or any of the other controversial ones this season, they have messed it up.
"Now, they'll say that things are better in the Premier League than they are abroad, but that doesn't wash with me.
"It is so messed up in every single way, there is 'deliberate', 'proximity', 'natural', 'unnatural' - there are so many different ways they have to interpret things and it isn't fit for purpose.
"For fans to be sat in the stadium and waiting for three, four minutes, or for however long it took today at Turf Moor, it doesn't seem right and it isn't fair."
He added: "I asked five of the guys in the room earlier are you certain that hit his arm? Four of the guys said no. It would be very simple for the law to say deliberate handball or not."
Despite tasting defeat, Parker was restrained in his response to the decision.
"Maybe a little bit of injustice. I've not watched it back. I saw it on the big screen and I was thinking it looks like his hand is beside his side," he said.
"I don't want to say too much because no doubt I'm going to get quoted and I might be wrong. It looks so, so harsh.
"In the modern day, we want perfection. Of course, there are elements of it that make it what it is. I've not seen it back, but offside is offside and if it's handball, it's handball."
Former Premier League official Darren Cann said despite Barnes' handball being accidental, it was "correctly disallowed".
"The handball law states that if a player scores in the opponents' goal immediately after the ball has touched their hand/arm, even if accidental, then it's a handball offence," he said.
"Barnes' handball was accidental, but was correctly disallowed under the current law.
"Perhaps the lawmakers Ifab, who coincidentally met in Cardiff today to discuss law amendments, will one day revert to only penalising deliberate handballs, but until this time, accidental handballs by the goalscorer will continue to be penalised."
