European champions Bayern Munich went top of the Bundesliga on Saturday as Thomas Mueller equalled Oliver Kahn's record for most league wins in the famous shirt in a 2-1 victory at Cologne. Mueller, 31, converted an early penalty to put the visitors on the way to a success which saw him match the tally of legendary goalkeeper Kahn on 260 league wins. Robert Lewandowski, who scored 10 goals in the opening five league games, was rested ahead of Bayern's midweek Champions League match at Salzburg and next Saturday's top-of-the-table Bundesliga clash at second-placed Dortmund.

"(We were) too nonchalant up front, even though the passion was there," said Mueller despite the reigning champions' victory. Serge Gnabry, who scored Bayern's second goal, admitted: "We let the opponent back into the game, it wasn't our best performance." An early header by Gnabry led to Cologne defender Marius Wolf giving away the 13th-minute penalty which Mueller scored. Gnabry added the second on the stroke of half-time when he rolled the ball into the net to finish a counter-attack. However, Cologne improved in the second half and substitute midfielder Dominick Drexler pulled back a late goal.- Leipzig crash - Later, RB Leipzig, who started the weekend top of the table, blew the chance to reclaim first place after losing 1-0 at Borussia Moenchengaldbach. The away defeat capped a week to forget for Julian Nagelsmann's Leipzig following their 5-0 thumping at Manchester United in the Champions League. Leipzig forwards Yussuf Poulsen and Dani Olmo both wasted chances while Gladbach had a goal by Alassane Plea ruled offside. Austrian winger Hannes Wolf, 21, who is on loan from Leipzig this season, sealed the win with his first Bundesliga goal on 60 minutes before Plea hit the post.
