Serge Gnabry scored twice as Bayern Munich beat Cologne in an entertaining Bundesliga encounter.

Robert Lewandowski opened the scoring on 50 minutes with a close-range finish from Jamal Musiala's cross.

Gnabry added a second eight minutes later, before the visitors pulled level with two goals in as many minutes courtesy of Anthony Modeste and Mark Uth.

Gnabry scored the 71st-minute winner with a powerful strike inside the box.

Lewandowski has scored in each of his last 12 Bundesliga appearances, with 19 goals in that run. The last time he played a game for Bayern without scoring was February.

It was a first league win of the season for Julian Nagelsmann's side after a disappointing opening-day draw at Borussia Monchengladbach.

Bayern paid tribute before kick-off to legendary striker Gerd Muller, who died at the age of 75.

Muller's former team-mates spoke on the pitch before a minute's applause as 20,000 fans returned to the Allianz Arena.
