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.
