Playing Bayern in your first match in charge is not ideal but interim 'Gladbach chief Horst Koppel, who stepped in to replace Holger Fach when he was sacked on Wednesday, kept a cool head -- and goals from Marcelo Pletsch and Joris van Hout made his job easier.

Replacing them there is Hansa Rostock, who lost a yawner to FC Nuremberg 0-2. With six straight home defeats, Rostock sets a Bundesliga record and is officially in a crisis.
Elsewhere, Schalke 04 manager Ralf Rangnick guided his side to a fifth straight league win on Saturday in a thrilling 3-2 victory over VfB Stuttgart. Brazilian Ailton scored after just forty seconds to register his third goal in as many matches and further striks from Levan Kobiaschvili (2) and Brazilian Lincoln (25) gave Stuttgart a mountain that proved too steep to climb.
"It's one of the best matches I've seen in the Bundesliga in years," said Schalke manager Rudi Assauer. "It was really back and forth. Stuttgart really managed to come back."

It was also a good day for Schalke's arch rivals Borussia Dortmund who notched their first home win of the season with Bayer Leverkusen on the wrong end of a 1-0 scoreline. Brazilian Ewerthon scored the only goal after 41 minutes.
