Second-half goals from Noni Madueke and Gabriel Martinelli fired Arsenal to a 3-1 victory in their heavyweight Champions League clash with Bayern Munich.
Madueke, back after two months out with a knee injury, scored his first Gunners goal before fellow substitute Martinelli pounced on a mistake from Bayern ‘keeper Manuel Neuer to stretch Arsenal's perfect record in the competition to five victories from five matches and leave them top of the 36-team table.
