Mario Goetze scored two goals as Bayern Munich eased to a 4-0 victory over promoted Paderborn and moved to the top of the Bundesliga on Tuesday.

Paderborn's hopes of achieving a huge upset were dashed quickly, as Goetze and Robert Lewandowski scored inside the first quarter of an hour. Goetze and Thomas Mueller then netted late in the match as Bayern brought down to earth the team that had come into the match as the surprise league leader.

Paderborn did not embarrass itself despite the big defeat and wasted several chances. The small club is making its debut in the top tier and has a budget 25 times smaller than that of Bayern and is dwarfed in all aspects by the German powerhouse and defending champion.

Bayern opened a two-point lead over Mainz, which blew a two-goal advantage and had to settle for a 2-2 draw at Eintracht Frankfurt.

In other matches, Schalke won 3-0 at Werder Bremen and Hoffenheim and Freiburg drew 3-3.

Paderborn's only claim to prominence before this season was a dubious one. The club, then in the third division, was involved in one of the one of the matches manipulated by referee Robert Hoyzer in 2004 in Germany's biggest match-fixing scandal.

This season, however, Paderborn is gaining attention for all the right reasons. By playing an aggressive pressing game, the club with a home ground that can house only 15,000 was undefeated after four matches and leading the league on goal difference.

It had the first chance of the match when Elias Kachunga's spectacular volley sailed high.

Bayern quickly seized control, though, to end Paderborn's promising start. Goetze, who scored Germany's World Cup winning goal against Argentina, picked up a backheel pass from Mueller to slot home in the eighth. Lewandowski doubled the lead in the 14th with a volley from the edge of the penalty box, but he appeared to be slightly offside.

Paderborn then found it hard to come out of its half, but when it did it nearly scored. Idir Ouali broke free but his weak shot was smothered by goalkeeper Manuel Neuer.

Lewandowski and Goetze wasted a couple of chances each before Paderborn somewhat settled down after the break.

Xabi Alonso, having an outstanding game, cleared a dangerous cross from Moritz Stoppelkamp, before Neuer was forced into a diving save from substitute Suleyman Koc, who had served prison time for armed robbery before getting a chance at Paderborn.

But Bayern struck again late in the game, with Goetze scoring in the 78th and Mueller in the 85th, both from close range.

"It was very important to make a statement. Paderborn was having problems from the start," said Arjen Robben, who helped set up Bayern's first goal and assisted on its fourth.
