Berlin: Borussia Dortmund regained top spot in the Bundesliga from Bayern Munich with a 3-0 win over Bayer Leverkusen to preserve their 100 percent record after five straight wins.
Dortmund have now won 11 games in all competitions, but are top only on goal difference from defending champions Bayern Munich, who have also won all five games this season after beating Darmstadt 3-0 away on Saturday.
Early form suggests there will be a title-race in Germany this season after Bayern won the Bundesliga for each of the last three years at a canter.
Dortmund took the lead when right winger Jonas Hofmann profited from a mistake by Leverkusen goalkeeper Bernd Leno to slot into an empty net on 19 minutes.
Leverkusen should have been awarded a penalty when Mexico striker Javier Hernandez was pushed in the area by Dortmund left-back Marcel Schmelzer on 53 minutes but referee Deniz Aytekin waved on play.
The hosts doubled their lead when left-winger Henrikh Mkhitaryan`s pass put Shinji Kagawa in behind the defence to slot past Leno on 58 minutes.
Pierre-Emerick Aubameyang netted Dortmund`s third and his six of the season to match Bayern`s Thomas Mueller`s tally as the league`s joint top scorer.
Augsburg picked up their first win of the season with a 2-0 victory at Hanover 96 thanks to goals by right-winger Alexander Esswein and Dutch defender Paul Verhaegh.
Earlier, Schalke`s Leroy Sane underlined his status as one of Germany`s rising junior stars with his club`s second-half winner to seal their 1-0 victory at VfB Stuttgart to leave the Royal Blues fourth.
On Saturday, Bayern, who are bidding to become the first team to win the German league four times in succession, went top of the table for 24 hours with a 3-0 win at Darmstadt for their fifth straight league win.
Arturo Vidal, Kingsley Coman and Sebastian Rode claimed their first goals of the season with Munich`s star forward Robert Lewandowski injured and Thomas Mueller on the bench.
Gladbach`s disastrous start to the season continued as they lost 1-0 at neighbours Cologne, thanks to Anthony Modeste`s second-half winner, in the Rhineland derby to stay bottom of the table with five defeats from five.
The victory left Cologne fifth while Gladbach, who lost their opening Champions League group stage match 3-0 at Seville on Tuesday, remain rooted to the foot of the table and Lucien Favre resigned on Sunday night.
Wolfsburg, who face Bayern away on Tuesday, celebrated their 70th birthday with a 2-0 home win over Hertha Berlin as Dutch striker Bas Dost netted twice to lift his side up to third.
After coming off the bench on 71 minutes, Dost netted the opener five minutes later, then drilled home a penalty on 89 minutes after a foul on Germany international Julian Draxler.
But Dost was later slammed by his coach Dieter Hecking for behaving `like someone had taken his toys away` in training having been subbed off in Wolfsburg`s Champions League win at home to CSKA Moscow last Tuesday.
Ingolstadt made history as the first Bundesliga team to win all three of their home games in their debut season in Germany`s top flight after Moritz Hartmann drilled home a 93rd-minute penalty which put the Bavarians fifth with a 1-0 win at Werder Bremen.
Bremen were reduced to ten men five minutes into injury time when midfielder Philipp Bargfrede was sent off for fouling Ingolstsadt`s USA international Alfredo Morales.
Hamburg were held to a goalless draw at home to Eintracht Frankfurt while Mainz are seventh after Friday`s 3-0 win at home to Hoffenheim when midfielder Yunus Malli claimed a hat-trick.
