(CNN) -- The streets of Berlin have turned black, red and gold as up to a million flag-waving fans gather in the German capital to welcome home the nation's World Cup-winning footballers. Germany's national side flew in from Rio de Janeiro -- where they beat Argentina 1-0 in extra time on Sunday to secure their fourth championship -- on Tuesday morning to a heroes' welcome. Mario GÃ¶tze (@MarioGoetze), who scored the winning goal at the Maracana, tweeted a photo of the team on the bus from the plane to the airport terminal, announcing that they had arrived home. Boarding an open-top Mercedes truck and trailer emblazoned with the years of their four World Cup victories -- 1954, 1974, 1990 and 2014 -- the team threaded its way through the city along roads lined with tens of thousands of cheering fans.
