Pep Guardiola's Bayern Munich host VfL Wolfsburg in the Bundesliga on Saturday eager to knock leaders Borussia Dortmund off top spot.

Bayern welcome 2009 German champions Wolves to Munich's Allianz Arena having now gone 31 Bundesliga games since their last defeat, when they went down 2-1 at Bayer Leverkusen in October 2012.

Guardiola's Bayern are second, but level on both points and goal difference with league leaders Dortmund, who host second-from-bottom Freiburg on Saturday, and the Bavarians are eager to finish the weekend on top.

Bayern face Manchester City on Wednesday in their second Champions League match and want to make sure of another three points against sixth-placed Wolfsburg.

"Only a win will count for us against Wolfsburg," insisted captain Philipp Lahm after Munich's 4-1 win over Hanover 96 on Wednesday sent them into the third round of the German Cup.

"We can be very happy with our recent performances, we are definitely on the right path."

Germany star Thomas Mueller scored twice against Hanover while veteran striker Claudio Pizarro, who netted a first-half goal, said Bayern are hitting form under Guardiola but must keep improving with City looming.

"When we use our chances, we are difficult to stop, but after going 2-0 up against Hanover, we stopped doing that," said the 34-year-old.

"It was okay to do that against Hanover but against a bigger team it can be deadly and we mustn't allow that to happen."

Having been 2-1 up at halftime, Bayern pulled away in the second half with a second goal from Mueller before France winger Franck Ribery hit their fourth.

Guardiola, who succeeded Jupp Heynckes as Bayern coach in June after the team won the treble of European, league and cup titles last season, said he was pleased to see Munich's fighting spirit come out.

"We played well, although in the last ten to 15 minutes of the first-half we lost our shape," said Guardiola.

"But I was surprised how we played in the second half. With our mentality, we started playing forwards again."

With five goals after the first two rounds of the German Cup, Bayern's Mueller again showed lethal finishing against Hanover.

"He is always dangerous, whether he scores with the head, chest or shoulder," said Lahm, after Mueller's first goal flew in off his chest.
