Bayern Munich strolled to a 4-0 win over Olympiakos at the Allianz Arena on Tuesday night in a dominant performance that saw Thomas Muller get on the scoresheet.
While the Bundesliga champions will be delighted with their own performance as they move clear at the top of Group F, their win also gives Arsenal hope of joining them in the knockout stages of the competition.
The Gunners needed to beat Dinamo Zagreb, which they did with a 3-0 win in north London, and had hoped that Bayern would do them a favour against the Greek side.
In turn, that means that Arsene Wenger will take his men to Greece next month knowing that they can still leapfrog their rivals and finish second in the group to join Bayern in advancing.
Douglas Costa, Robert Lewandowski and Kingsley Coman all got on the scoresheet for Pep Guardiola, and not even a sending off for Holger Badstuber before the hour mark could stop them from securing another impressive result at home.
The German giants will undoubtedly take great confidence from their last two games which have seen them score nine and concede just once, and many of their rivals will be keen to avoid them in the round of 16.
