Cameroon striker Mohamadou Idrissou was both goal-scorer and provider for Moenchengladbach as they upset Leverkusen 6-3 on Sunday in a nine-goal thriller on a weekend of shock results in the Bundesliga. Leverkusen's Germany goalkeeper Rene Adler had a day to forget as his defence capitulated leaving coach Jupp Heynckes red-faced.
"'Gladbach played very well," admitted Heynckes. "We made a mess of our defensive organisation. "We invited 'Gladbach to the party and they punished us."
After Bayern Munich were beaten at Kaiserslautern on Friday, Wolfsburg allowed a 3-0 lead to slip to a 4-3 defeat by Mainz on Saturday as Schalke went down at home to Hanover on a bad weekend for the German league's top teams.
Leverkusen fielded Germany star midfielder Michael Ballack - who was booed off when he was replaced in the second-half - as well as Adler and striker Stefan Kiessling.
But they were out-played by 'Gladbach as midfielder Patrick Herrmann netted twice for the guests which were both set up by Idrissou, who scored himself in the second-half. On Sunday evening, Stuttgart's poor season start season continued as they were well beaten 3-1 at home by Dortmund.
The guests raced into a 3-0 lead after just 37 minutes as Christian Gross-coached Stuttgart were torn to pieces.
It started when defender Marcel Schmelzer fired in a cross which deflected off Dutch defender Khalid Boulahrouz and into the net after five minutes. Striker Lucas Barrios and midfielder Mario Goetze then both netted before Germany striker Cacau pulled a consolation goal back for Stuttgart, who are bottom of the table after two games.
Hoffenheim are joint early leaders with Kaiserslautern after Ghana defender Isaac Vorsah headed a late goal on Saturday night that gave them a 1-0 win at newcomers St Pauli.
