BAYERN knocked Arsenal out of the Champions League in 2005, 2013 and 2014 and should make it four in a row.
The Gunners won their group and expected an easier draw but landed unlucky with the German cracks.
They're not as smooth a machine as the one that rattled in goals under Pep Guardiola or Jupp Heynckes but Carlo Ancelotti's men are tough to beat.
Bayern are a best 1-2 with the likes of McBookie to win tonight and 2-5 at Paddy Power to qualify.
Arsenal are 63-10 with Marathonbet to triumph in Munich while a draw that Arsene Wenger would bite your hand off for is 72-20 at Marathonbet.
Bayern are seven points clear at the top of the table closing in on a fifth consecutive league title but recent form gives the Gunners a bit of hope and are 9-4 at bet365 to qualify.
In recent weeks they've struggled to beat Freiburg, Werder Bremen and Ingolstadt and dropped points to Schalke but do have Robert Lewandowski.
The Polish hitman is always a danger and his 30 goals this season and nine in 10 matches. He is 14-5 at McBookie to score first and just 8-15 at McBookie to net at any time.
In their two previous knockouts to the Germans Arsenal avoided defeat at the Allianz Arena – winning 2-0 and drawing 1-1 after losses at the Emirates.
Arsenal haven't drawn a blank away from home since August when they were held 0-0 Leicester and Bayern have kept just nine clean sheets in 20 league games so both to score has chance at 4-5 with Stan James.
Real Madrid are 4-7 with BetVictor to take a lead to Napoli for the second leg and they'll need it in a game where both teams should score. Cristiano Ronaldo is 29-10 at McBookie to score first.
