Chelsea have vowed to take “the strongest possible action” against fans found singing an anti-Semitic chant.
The club condemned the song about Alvaro Morata by their fans during Saturday’s 2-1 win over Leicester City.
Chelsea head of communications Steve Atkins said offenders will be banned if there is sufficient evidence.
The chant about Morata, who scored against Leicester, was used to abuse London rivals Tottenham, who have a large Jewish fanbase.
