Celtic extended their lead at the top of the Scottish Premiership.
Ross County Manager Jim McIntyre
Looking to continue the form that saw them book their place in the League Cup final, the Hoops made a perfect start as Patrick Roberts' great run resulted in the opening goal just three minutes into the clash at the Global Energy Stadium.
Celtic's Patrick Roberts opened the scoring
But then came the controversy that left McIntyre infuriated following the game. First, Leigh Griffiths avoided a second yellow after appearing to lash out at Andrew Davies while Craig Gordon avoided a more serious punishment after being booked for taking out Liam Boyce late on in the second-half.
And Celtic were able to capitalise as they scored three more times in the final 10 minutes to secure the emphatic win which has taken them seven points clear of their nearest challengers in the Scottish Premiership.
McIntyre felt Griffiths was lucky to not be dismissed
But following the loss, McIntyre expressed his disappointment at the apparent leniency towards the two Hoops stars.
"First, it was definitely a second booking on Leigh Griffiths – he has a wee swipe at Andrew Davies, but we don't get it. If that’s our player, he's off," he said, as reported by The Scottish Sun.
McIntyre was also annoyed Gordon stayed on the pitch
"Then you had Craig Gordon’s challenge – it's high, it's dangerous, it's reckless. If an outfield player went in that high, he'd go off the park.
"You're scratching your head.
"There was that inconsistency there tonight. It is disappointing, and Alan Muir is a good referee, but I'm disappointed."
Regardless of whether the pair should have been dismissed, Celtic boss Brendan Rodgers will have been delighted by the way that his side capitalised on their fortune to put the game beyond doubt through goals from Stuart Armstrong, Scott Sinclair and Moussa Dembele.
