Pierre-Michel Lasogga scored twice as Hamburg SV crushed rock bottom Borussia Moenchengladbach 3-0 on Friday to extend the home team's worst-ever start to a league season to four consecutive defeats.
The win lifted Hamburg, who needed a relegation playoff to stay up last season, to seventh on six points.
Gladbach, third in the Bundesliga last season, will go into their maiden Champions League group stage match at Sevilla on Tuesday in abysmal form and with the pressure piling on coach Lucien Favre.
The visitors took the lead when Lasogga, who struggled with injuries and form last season and has been relegated to second choice this term, pounced on Tony Jantschke's miscued pass before rounding keeper Yann Sommer after 11 minutes.
The 23-year-old striker, who is battling against Ivica Olic and Sven Schipplock for a place and was making his first start of the season, doubled the lead just before the break when he headed in a corner.
Nicolai Mueller chipped Sommer with a delicate first touch from Hamburg keeper Jaroslav Drobny's 60-metre kick to grab a spectacular third goal early in the second half.
On Saturday, Bayern Munich take on Augsburg while fellow co-leaders Borussia Dortmund meet Hanover 96 as both teams look to maintain their 100 percent starts.
Cavani scores twice but PSG's 100 percent record goes
Champions Paris St Germain dropped their first Ligue 1 points of the season on Friday when, despite two goals from Edinson Cavani, they were held to a 2-2 home draw by Girondins Bordeaux.
Cavani gave the capital club the lead in the 27th minute when he sent a right-foot shot high into the net.
Wahbi Khazri laid on the equaliser three minutes later as his cross was met by Henri Saivet's head six metres out.
PSG went back in front after 34 minutes when Uruguay striker Cavani found the top corner from a free kick.
Saivet was sent off for a second bookable offence in the 77th minute but Bordeaux's 10 men fought back to level through Khazri a minute later.
PSG are still top with 13 points from five matches while Bordeaux occupy ninth position on six points.
Stade de Reims and Stade Rennes, who are joint second with nine points, play over the weekend.
Reims travel to Toulouse on Saturday while Rennes visit Nantes the following day.
PSG launch their Champions League campaign with a home game against Group A rivals Malmo of Sweden on Tuesday.
