Lewandowski's records drag Bayern back to dominate the Bundesliga after a period of fogging taking advantage of the braking of the other big names.
The Bavarians have an uncomplicated engagement with Hoffenheim while the big match is between the pursuers Leipzig (who comes from a less than optimal series) and Leverkusen (who after beating Dortmund lost at home to Wolfsburg).
Haaland's team, which replaced coach Favre in December, comes from two knockouts and needs a shock.
The commitments of Frankfurt, Moenchengladbach and Wolfsburg are easier.
