There was a big billing going into this game considering the history between the two teams, the presence of two talented managers and two strong squads on either side.
Barton played his part in the build-up, exchanging insults with Hoops captain Scott Brown on radio and social media.
But he was unable play a big part in the game as Rangers struggled to cope with an impressive Celtic side before being hamstrung by Philippe Senderos’ second-half sending off.
Moussa Dembele’s hat-trick alongside goals from Scott Sinclair and Stuart Armstrong were rewards for a strong display from Brendan Rodgers’ side.
And among the delighted Hoops supporters on social media, Collymore – who has publicly shared his support for Celtic in the past – got involved and couldn’t resist taking a pop at Barton.
The pair have clashed on Twitter before and Collymore had to have his say on a bad day for Barton and Rangers:
Celtic’s 5-1 win victory puts them four points ahead at the top of the Scottish Premiership table and will leave Gers fans in no doubt their team needs to improve moving forward this season.
