Celtic beat St Johnstone 3-1 in the Scottish Premiership on St Stephen's Day.
A double from Liel Abada gave Celtic a two goal advantage at the break. Chris Kane got one back from the home side in the second half before Nir Bitton sealed the win for Celtic in the 82nd minute.
In the post-match analysis, Kris Boyd questioned if Abada's first goal should have been allowed. He also suggested that VAR should be introduced to Scottish football to aid referees. James McFadden agreed that it was a handball and echoed Boyd's call regarding VAR.
"When I see it from that angle, it's a handball," Boyd told Sky Sports.
"It hits his hand and goes into the back of the net. Get VAR into Scottish football. We've got this [winter] break, get working on it - I know it's not going to happen.
"There are so many incidents happening that are talking points. People will blame the referee, blame the linesman - they have no chance of seeing that from that position, they need help. Find the funds from somewhere to get VAR into Scottish football."

In the 63rd minute, with Celtic leading 2-0, there were shouts for a penalty after Tom Rogic went down following a clash with St Johnstone's James Brown.
"At the time, you're thinking 'Why has Tom Rogic gone down?'" said Boyd.
"But you go back and think there's an opportunity for a penalty in there. That's where the referees do need help.
"It was probably the closest that [James] Brown managed to get to any Celtic player all day. There's a little barge in the back. It would be interesting to see if you get a referee and ask them [what they think]. For me, it's borderline. If Bobby Madden (the referee) had to go to the sideline or somebody is in his ear, I'm sure they'd have looked at it again."
