Bayern Munich trimmed Borussia Dortmund's Bundesliga lead back to three points thanks to Leon Goretzka's double against Hoffenheim.
Leon Goretzka's maiden Bundesliga brace guided Bayern Munich to a hard-earned 3-1 win at Hoffenheim in their first fixture of 2019.
Victorious in each of their final five league matches last year, the defending champions picked up where they left off as Goretzka struck twice in 12 first-half minutes.
Hoffenheim took a 10-match unbeaten streak into Friday's encounter but were unable to build on Nico Schulz's fine 59th-minute strike in Julian Naglesmann's 100th match at the helm in Germany's top flight.
