FRANKFURT, Germany (AP) — Bayern Munich kicked off its bid for an unprecedented fourth straight Bundesliga title by cruising past hapless Hamburger SV 5-0 on Friday at Allianz Arena in Munich.
In the opening match of the Bundesliga season, defender Medhi Benatia scored the first goal by heading in a free kick from Xabi Alonso in the 27th minute.
Bayern dominated the match but Hamburg held on well until falling apart in the second half.
Thomas Muller scored twice after the break and Robert Lewandowski and newcomer Douglas Costa added the other goals.
"We are still hungry despite all the success we've had," Muller said. "We kept on playing even after we scored the second. We want to keep this mentality."
Hamburg barely avoided relegation last season in a playoff and hardly created any chances against the defending champion, which had nearly 80 percent of the possession.
"We have to send the right signals, we don't want anyone to think they can compete with us," Bayern's director Matthias Sammer said.
Having conceded 30 goals in its last five league visits to Munich, Hamburg began cautiously, using six defenders and closing the space.
"It was very difficult, they only defended but we played better in the second half," Bayern coach Pep Guardiola said.
Guardiola is in the final season of his three-year deal and has been vague about his future.
Lewandowski used a poor clearance to double Bayern's lead in the 52nd and then fed Muller for his first in the 69th. Muller rounded Hamburg's goalkeeper Rene Adler as Hamburg's game plan started unraveling.
Muller scored his second in the 72nd when he connected with a cross from Douglas Costa. The speedy winger caught a difficult ball on the right wing in his first Bundesliga match and sent a perfect cross with the outside of his left foot for Muller to head in.
Costa then used some poor defending from Hamburg to score his first Bayern goal in the 87th, driving home from just outside the box.
"We played really well in the first half but then we started making mistakes and we couldn't keep them from scoring," Adler said.
