Pep Guardiola is a Spanish soccer manager for a German team expected to answer media questions in English. So you'll forgive him if sometimes he drifts, linguistically.
It might be hard to tell at first with the German dub explaining what's happening, but at the :10 mark, you can hear Guardiola switch mid-sentence from English to Deutsch. He continues happily until someone gently reminds him, causing Guardiola to rub his head in frustration and jokingly ask "Warum Englisch?" ("Why English?").
