Berlin - Philippe Coutinho scored a hat-trick as Bayern Munich signalled their return to form with a 6-1 thrashing of Werder Bremen in the Bundesliga on Saturday.
Two goals in three minutes at the end of the first half however turned the game on its head, with Coutinho and Robert Lewandowski both scoring to fire Bayern into a 2-1 lead.
Marco Reus scored his first away goal of the season with a stunning volley from the edge of the box, before Jadon Sancho, Thorgan Hazard and Nico Schulz all scored in the second half.
Union Berlin's recent run of victories came to an end following a 1-1 draw against lowly Paderborn. Union, who had won four of their last five before travelling to Paderborn, started well, scoring through Marcus Ingvartsen in the seventh minute, before Paderborn equalised via Kai Proger in the 33rd.
