Through observational data collected over a two-year fieldwork project, I describe how this institution implemented this partial English-medium instruction program for the first time in Spain, as part of its internationalisation mission. I then focus on the students' perspectives towards the officialisation of English as the third language of the Catalan tertiary education system. I analyse 30 argumentative essay assignments which show that students mobilise both favourable and unfavourable discourses on this language. They envision English as an asset for employability and educational excellence, and as a post-national 'democratic' code for intercultural communication. However, they also construct it as a politicised language which threatens linguistic diversity. I conclude that these conflicting attitudes respond to the particular sociolinguistic configuration of globalised universities in Barcelona. This contributes to a more nuanced understanding of the students' range of situated stances concerning the linguistic regimes that govern the European multilingual policies of higher education, in late capitalism.
