In March 1975, West Germany – the newly crowned world champions – came to London’s Wembley Stadium for a friendly against England.Among the German squad was a 28-year-old striker who’d already attracted a lot of attention from the British media: not because he’d been hailed as the new Gerd Müller, Germany’s legendary goal scorer, but because of the colour of his skin.Erwin Kostedde was the son of a white German mother and a black US soldier, and he had been on the receiving end of racism for most of his life – even during what he considered to be the best years of his career, at Kickers Offenbach. He talks to Kristine Pommert about how racist taunts from supporters and even fellow players affected his game – and how he feels about being a trailblazer for young black players today.
