Aston Villa says it is "disgusted and appalled" by a social media video showing a group of supporters "chanting a racist song" at Norwich City on Saturday.
The footage, which has been widely circulated, appears to show the small section of supporters using lyrics that the club branded a "cheap and insulting stereotype" about Zimbabwe international Marvelous Nakamba. There is also a reference to his Villa team-mate John McGinn.
In a statement posted on the club's official website, Villa says it "wholly condemns" the chant and has urged other supporters to help identify those in the video.
The statement read: "Aston Villa is disgusted and appalled by footage circulating on social media of supporters chanting a racist song which makes reference to two of our first team players.
"The club wholly condemns the chant and urges other supporters to help us identify those responsible.
"Chants of this nature besmirch the good name of Aston Villa football club and our fans. If the perpetrators are identified they will be dealt with in the strongest manner by the club and be reported to the police immediately.
"Our security staff will be vigilant at forthcoming games to ensure that anybody attempting repetition of this chant will be dealt with severely.
"We know we can rely on the assistance of the majority of our fans to eradicate this toxic behaviour immediately."
