Celtic triumphed 4-3 in a madcap Premiership encounter with Hearts.
James Forrest followed on from his hat-trick against the Jambos' Edinburgh rivals Hibs last weekend to head the Hoops into an early lead, following a bright start from Robbie Neilson's men. It was a historic day as VAR was used in a domestic match for the first time at Tynecastle and a lengthy check had to make sure Anthony Ralston's headed effort into the bottom corner didn't stand.
More VAR dismay was to come for Hoops boss Ange Postecoglou, as a foul by Cameron Carter-Vickers was overturned from no foul to penalty, which Lawrence Shankland dispatched, and then Michael Smith's handball in the box was inexplicably not given. They got back in front through Daizen Maeda and Giorgos Giakoumakis but not before VAR had a say again with Shankland making it a hat-trick from the spot. Greg Taylor then rose from the bench to finish off this crazy game and here are three things we learned from the Celtic performance.

Spin the wheel
Postecoglou spoke after the Motherwell game of making selection change after selection change in his XI's at Parkhead.
Only five remained from that game but three of those drafted in scored and another who was benched came on to score the winner. It proves it's a working method.
Renansainnce man
It was perhaps easy to forget about the sheer impact Forrest has made at Celtic amid a raft of exciting attackers arriving in Glasgow.
But four goals in two games prove he's more than capable of keeping up with them after some perhaps wrote him off.
VAR drama
Yep, it's finally here and oh boy did it deliver on the fears people had with it. Long delays and a debatable call, any hope for a calming in refereeing scrutiny took a dent here.
Smith perhaps got away with one but there's another debate on how rules are interpreted. Then Shankland's second of the penalty of the day had to be retaken. It was hard to keep track, that's for sure.
