UEFA is considering whether to open a disciplinary case against Partizan Belgrade after the Serbian club's fans displayed an anti-Semitic banner during a Europa League game against Tottenham.
Partizan supporters on Thursday displayed a banner that mimicked the logo for British TV sitcom "Only Fools and Horses," using the word "Jews" and a vulgar term.
UEFA said it is looking into the matter but has not yet launched a formal investigation.
Tottenham manager Mauricio Pochettino said after the 0-0 draw that "this is a shame, very disrespectful and unacceptable."
Tottenham has traditionally drawn a large fan base from the Jewish communities in London.
