Celtic have responded to allegations made by Rangers that Colombia striker Alfredo Morelos was racially abused at Parkhead on Sunday.
Video footage has emerged on social media showing Morelos leaving the field following his red card amid shouting from the home support.
The 23-year-old responded with a throat-slitting gesture, something the Gers have since denied that it had any sinister connotations associated to it.
A Celtic spokesman has since said they would welcome a full investigation into the claims made by their city rivals.
“We are aware of the gestures made by the player [Alfredo Morelos] towards Celtic supporters.
“We have received no reports of any racial abuse but would fully investigate any should these be brought to our attention.”
A Rangers spokesperson had previously told the Scottish Sun that they believed Morelos had been the victim of racial abuse.
“We believe Alfredo was racially abused and we would expect now that all measures will be taken to identify and deal with those responsible.”
Gers officials are understood to be incensed at the treatment that Morelos received as he made his way off the pitch and towards the tunnel.
Morelos saw red in the closing stages of a fiery Old Firm derby after being shown a second yellow card for diving to win a penalty.
He had been booked for a foul on Celtic skipper Scott Brown five minutes before the end of normal time.
Meanwhile, Rangers have also released a lengthy statement in the wake of Sunday’s 2-1 win over Neil Lennon’s men – reiterating their desire for VAR to be introduced to Scottish football.
“The speed at which the modern game is played also means it is extremely difficult to make split-second calls with the degree of certainty required,” the statement opened.
“We believe the introduction of VAR would help referees enormously and reduce the number of wrong decisions which sometimes have a dramatic effect on the outcome of matches.
“In recent weeks, Rangers has suffered from errors of judgement but it is our strong view that VAR would be to the benefit of everyone and in particular the referees themselves.”
