Hamburg moved to the top of the Bundesliga with a 3-1 home win over Cologne.

A Paolo Guerrero brace set HSV on their way and Piotr Trochowski's late penalty sealed matters after substitute Adil Chihi had pulled one back for the visitors.

The result sees Hamburg climb to the summit, ahead of Bayer Leverkusen on goals scored.

Werder Bremen moved up to third courtesy of a 3-2 triumph at Hertha Berlin in a match which saw all five goals scored in just over half an hour in the second period.

Mesut Ozil made the breakthrough for Bremen 12 minutes after the restart and Tim Borowski doubled their advantage in the 74th minute.

Naldo made the points safe with a third seven minutes from time after Lukasz Piszczek's free-kick had briefly given the hosts hope. Patrik Ebert's last-minute goal proved little more than consolation.

Arjen Robben made a dream debut for Bayern Munich on Saturday as he scored twice in their 3-0 win over champions Wolfsburg.

Bayern coach Louis van Gaal initially left the new arrival from Real Madrid on the substitutes' bench, but with his side only leading 1-0 at half-time thanks to a strike from Mario Gomez he decided to introduce his compatriot after the interval.

Robben combined well with Franck Ribery to net a brace and seal Bayern's first win of the season to take them up to seventh in the table and erase memories of the club's worst start to a league season in 43 years.

Manuel Friedrich scored at both ends in the first half as Leverkusen came from behind to secure all three points against Bochum with a 2-1.

Stefan Kiessling completed the recovery with the winner just over 20 minutes before the end as Leverkusen finally made their domination count.

Freiburg claimed their first win since their return to the Bundesliga, ending Schalke's unbeaten start to the campaign with a 1-0 success.

Cha Du-Ri hit the only goal towards the end of the first half to end a run of two successive defeats for the visitors.

Carlos Eduardo snatched a barely-deserved 1-0 victory for Hoffenheim at Hannover.

The home side should have been leading comfortably in the first half only to be stung five minutes before half-time when Eduardo popped up to convert the visitors' first chance of the game.

Eintracht Frankfurt forward Ioannis Amanatidis went from victim to villain to hero in an eventful 1-1 draw against Borussia Dortmund.

Amanatidis was denied a perfectly good goal by a poor decision from the linesman in the 34th minute, and then was at fault in the second half when Dortmund took the lead through Mohamed Zidan.

But he made amends a few minutes later to ensure the points were shared in a game where chances were at a premium.

Nurnberg are still searching for their first Bundesliga victory of the season following a 0-0 draw at Stuttgart.

On Friday night, Mainz missed the chance to go top after losing their first game of the season 2-0 at Borussia Monchengladbach on Friday night.
