BERLIN (AP) — Bayern Munich’s first defeat of the season couldn’t have come at a worse time for St. Pauli. After losing eight games straight in the Bundesliga, the promoted Hamburg-based team had hoped Bayern might have an off day this Saturday, complacent after another gala performance in the Champions League. But Bayern slumped to a 3-1 loss at Arsenal on Wednesday after mistakes from goalkeeper Manuel Neuer and defender Dayot Upamecano, and will be looking to make amends in front of its own fans when Alexander Blessin’s team visits.
