In keeping with the approaching World Cup, Netflix is releasing the documentary “Poldi” about the former German national player Lukas Podolski. Since Thursday, the footballer’s 41st birthday, the work has presented itself as quite unusual for a classic celebrity documentary. At the beginning, football greats like Joachim Löw, Oliver Kahn, Toni Kroos and Thomas Müller sit down to talk about their time together with Podolski.
