MUNICH (Reuters) - Defending champions Bayern Munich secured their first win of the Bundesliga campaign with a 3-2 victory over battling Cologne on Sunday thanks to Serge Gnabry's double and a Robert Lewandowski strike.

Gnabry thundered the ball past Cologne goalkeeper Timo Horn in the 71st minute of the contest at the Allianz Arena to settle his team's nerves, after the visitors had struck through Anthony Modeste and Mark Uth to make it 2-2.
