Standard Sport's Dan Kilpatrick identifies three key issues ahead of Tuesday's Champions League group meeting with Spurs at Tottenham Hotspur Stadium.
Can Spurs stop Lewandowski?
The prolific Pole has scored 12 goals in 11 matches this season and currently outscores 10 of the 18 Bundesliga clubs.
Lewi is one of the few top European strikers Jan Vertonghen has never faced and the centre-half and his partner Toby Alderweireld have a massive test to keep him quiet.
Ndombele must make his mark
Spurs paid a club-record fee for Tanguy Ndombele largely because of his Champions League form for Lyon.
The Frenchman (above) will be expected to be definitive in games like this one, although it is still early days for him at Spurs.
Test for Spurs’ full-backs
Bayern may have lost Arjen Robben and Franck Ribery, but their threat from the flanks is barely diminished through Serge Gnabry and Kingsley Coman.
They pose a big threat to Ben Davies or Danny Rose (above) and whoever plays at right-back.
