Müller tops Messi and Ronaldo
Thomas Müller has become the youngest player in history to chalk up 50 Champions League victories. The Bayern youth product passed the remarkable milestone in the home meeting with Olympiacos at the age of 26 years, two months and 11 days -- earlier than both Lionel Messi (27 years, four months, 12 days) and Cristiano Ronaldo (28 years, one month). The German record was previously held by Bastian Schweinsteiger (29 years, three months, four days).
Club record equalled
Since a 4-0 defeat to Real Madrid in the 2013/14 semi-finals, Bayern have won all nine subsequent Champions League home matches. The victory over Olympiacos equalled the club record in the competition, set between September 2011 and December 2012.
All-clear for Robben
Arjen Robben returned to a Champions League starting line-up for the first time in 258 days on Tuesday but was substituted after just 33 minutes due to a minor sprain. However, the Dutch winger was brought off as a purely precautionary measure.
Badstuber's bittersweet comeback
Holger Badstuber started a match for Bayern for the first time in seven months on Tuesday night, but after a solid first half, the centre-back's comeback turned sour when he was shown a straight red card after 52 minutes, his second sending off in his 36th Champions League appearance.
Alaba not in squad
David Alaba missed the Olympiacos clash with injury, as the Austrian's ankle injury sustained away to Schalke on Saturday failed to heal. It was the first time Alaba has missed a competitive match for Bayern this term.
Arsenal or Olympiacos? Showdown beckons
Bayern are guaranteed to finish top of Group F and the trip to Dinamo Zagreb in two weeks' time is a dead rubber from a Munich point of view, but Olympiacos and Arsenal will go head-to-head for the runners-up spot. Arsenal are now up to six points, still three off Olympiacos, after beating Dinamo 3-0 at home on Tuesday. The Gunners must beat the Greeks in Piraeus on the final matchday while also prevailing in the direct comparison: the first meeting in North London ended in a 3-2 away win.
