From daily The Morning Star in Britain, 26 July 2020:

Leftist clubs around the world

SOME of the biggest clubs in the world have strong leftist elements, like Celtic, Liverpool, Boca Juniors and Olympique de Marseille.

Meanwhile German second-tier outfit St Pauli remains a global lightning rod for the left’s football network, with fan groups across the globe from Buffalo to Belfast, and friendships with clubs throughout Europe, many of whom we have covered in this series.

Then there are less well known but equally passionate antifa fan groups around the world, from Standard Liege (Belgium), Adana Demirspor (Turkey), Virtus Verona (Italy), Portland Timbers and Seattle Sounders (United States) and Tennis Borussia Berlin (Germany), to non-league clubs like Clapton in east London and Altona 93 in Hamburg.
