The aim of this study is to analyse online expressions of rivalry and hate speech in relation to antisemitic and philosemitic discourse(s) in Dutch professional men’s football (soccer). We collected data from Twitter using the Twitter API and scraped Tweets relating to a match between the supposedly ‘Jewish’ club Ajax and its rival Feyenoord on 17 January 2021. A selection of the collected Tweets was analysed more in depth using narrative digital discourse analysis to interpret the Tweets. The research shows that antisemitic chants and slurs find their way towards the online domain, sometimes explicit and other times implicit. The analysis elaborates how these Tweets, while seemingly targeted towards the football rival, contribute to an exclusionary discourse in which being a ‘Jew’ is not wanted and contribute to the normalization and reproduction of antisemitism in football.
