Rangers claim Alfredo Morelos was subjected to racist abuse by Celtic fans in Sunday’s Old Firm clash at Parkhead.
The Ibrox club believe the 23-year-old Colombia international was targeted after he was sent off by referee Kevin Clancy in the closing stages of the Light Blues’ 2-1 victory, after picking up the second of two yellow cards.
A Rangers spokesman said: “We believe Alfredo was racially abused and we would expect now that all measures will be taken to identify and deal with those responsible.”
The Parkhead club responded with a statement which read: “We are aware of the gestures made by the player towards Celtic supporters.
“We have received no reports of any racial abuse but would fully investigate any should these be brought to our attention.”
