MD14 Saturday, while Jadon Sancho led leaders Borussia Dortmund to a 2-1 derby win at Schalke. Lewandowski scored twice in an impressive 3-0 home win against Nuremberg to lift Bayern up from fourth to second in the table, but they remain nine points behind Dortmund. Bayern will drop back to third when Borussia Moenchengladbach beat Stuttgart 3-0 at home on Sunday.

Thomas Delaney's first-half header for Dortmund was cancelled out by a Daniel Caligiuri penalty for mid-table Schalke before Sancho struck at the Veltins Arena.

However, Sancho hit the winner by going clear in the box after trading passes with Raphael Guerreiro and tapping home.
