Watch Celtic ball boys goad Allan McGregor as Rangers keeper suffers Parkhead pain pile on

As if having a 60,000 strong baying mob of Celtic fans in the stand at Parkhead wasn't enough, Rangers keeper Allan McGregor had a few extra punters rubbing his nose in the defeat to their fierce rivals.

It came in the shape of the ball boys behind his goal who taunted him mercilessly at the veteran Ibrox No. 1 was forced to pick the ball out of his net after twice being put in trouble by his defenders during the 3-2 defeat at the home of the champions.

One eagle-eyed Celtic supporter shared a clip on social media that he captured during an afternoon of celebration for Ange Postecoglou's men who moved a dozen points clear of Michael Beale's light blues to effectively seal two-in-a-row. Kyogo netted a double while Jota finished off the scoring for the home side after half-time to cancel out a double from James Tavernier on another enthralling derby day.

The clip shows McGregor - making his 501st appearance for Rangers - taking sip from his water bottle before going behind his goal to wrestle the ball from one of the ball boys after he could be seen mouthing towards the 41-year-old.
