Scott Sinclair gave Celtic the perfect start to the final Old Firm game of the season when he put his side 1-0 from the penalty spot after just seven minutes of play at Ibrox on Saturday afternoon.
As Sinclair ran to the supporters, one fan in the crowd was clearly caught by the Sky Sports cameras making monkey gestures towards the celebrating goalscorer.
It was undoubtedly idiotic behaviour by the fan.
Following the 5-1 win for Celtic, Sinclair condemned the fan's actions.
What a team performance yet again, the fans were right behind us from start to finish...

...just a shame to end the game and seeing the ignorance of people no matter what team u support there is just no need for racism!

Moussa Dembele, Celtic's star striker who was unable to play on Saturday due to injury, also castigated the fan.
