Bobby Madden insists Camilo Duran's goal for Celtic against Dundee United should have been disallowed.
Martin O'Neill's side eased past the Tannadice side in the end after surviving a few scares with the hosts hitting the woodwork on multiple occasions.
One of the four goals proved very contentious though after the ball struck a grounded Kasper Hogh's hand before being turned in by Camilo Duran.
There was much confusion around it, especially after Falkirk had a similar goal chopped off the in the Premiership, but referee's chief Willie Collum released a statement explaining why the Celtic one stood.
However, former referee Madden disgrees.
Speaking on Instagram, he said: "A much discussed decision at Tannadcie yesterday was Celtic's second goal. Ball contact on the arm of a teammate of the goalscorer. I’d like to point you in the direction of a fantastic new platform released by UEFA just six days ago called Player Online. You can get that on their social media or their website.
"This platform was designed to inform everyone interested in football regarding the laws of the game, guidelines, criteria, and media examples. All the decisions are covered. After Celtic's disallowed goal yesterday, some supporters were confused. This platform clears that up.
"Let's start with UEFA's law in its current phase. We go to VAR and accidental handball in the buildup. You can see here we talk about the criteria. It says that any handball that's missed in the buildup should be identified by VAR and the goal disallowed. The rationale says a goal attained after a handball cannot stand.
"It uses this clip between Switzerland and Spain as an example. In this clip, the goal is scored after an accidental handball by the hand of the teammate long before the goal was scored. UEFA are absolutely clear that this goal should be disallowed. They also talk about a game between Inter MIlan and Liverpool in the Champions League last season for this accidental contact where a teammate headers the ball onto the arm before it goes to another teammate who also scored. UEFA were clear that this goal should also be disallowed.

"We had an incident in the opening weekend of the Scottish season where Falkirk were denied an equalizer against Saint Mirren. It was disallowed for in-play contact on the arm of a teammate directly before the ball goes to a teammate to score. It's not the first time it's happened. The challenge is understanding why there are four instances here where the VAR has only intervened in three cases. This platform is an absolute godsend and can act as a guide to everyone involved."
Collum's statement read: “The entire incident was checked, including the handball. The ball clearly strikes the hand of the Celtic attacker, however this is not a punishable handball as it is a consequence of his playing action and is completely accidental.
“The laws of the game are clear regarding handball and an immediate goal being scored. The offence only applies when the player who handled the ball is the one who subsequently scores.
“As another attacker scored, this provision does not apply.
“We note that at half time this was compared to the Falkirk disallowed goal from week one (in the Premiership). The VAR deemed that handball to be punishable by law.
“In our opinion however, these are completely different incidents and should be considered comparable.”
