Nil By Mouth have urged Celtic and Rangers to come together and condemn sectarian abuse after Alfredo Morelos was branded a "wee orange b******" by a yob in Glasgow.

Morelos was subjected to the abuse on Mitchell Street in footage which emerged on social media earlier this month.

The Rangers hitman was hit with the verbal slur by a man passing by in a car.

Rangers accuse Celtic fans of 'racially abusing' Morelos

It comes less than a week after Morelos' Gers earned a 2-1 victory over Celtic at Parkhead.

Plenty of fans criticised the abuse in response to the clip but anti-bigotry charity Nil By Mouth has called for more action to be taken.

And the charity director, Dave Scott, has blasted the "moron" for his comments and asked for a joint statement from Celtic and Rangers in a bid to deter fans from spreading hate.

He said: "This is the latest dismal example of people completely overstepping the mark with footballers in the city.

"They have the right to go about their lives without having to endure the sort of nonsense served out by bigoted morons who think they have some sort of right to abuse a person going about their business. 

"I’d really like to see some sort of joint statement from both clubs to the effect of - ‘we are rivals on the pitch, but human beings off it’ to try and stamp out this behaviour."

Celtic and Rangers have both been approached for comment by Glasgow Times.
