Robert Lewandowski scored all four of Bayern Munich's goals as they picked up a last gasp 4-3 win against Hertha Berlin. After going two goals up Bayern were pegged back to 2-2 before Lewandowski completed his hat-trick by turning home Thomas Muller's knock down from a free-kick with five minutes to go. Jessic Ngankam thought he'd got Hertha a point with a late header, before the irrepressible Pole won and then converted a 93rd minute penalty.
