BERLIN - Bayern Munich were likened to a Formula One car on Saturday, out-racing some of the clapped-out runabouts in the Bundesliga.
Bayern warmed-up for Wednesday's Champions League visit of Viktoria Pilsen with a 4-1 drubbing of Mainz with Germany's Mario Goetze making the difference but only after being a goal down at the break.
"We were like a 1970s VW Beetle and you can't dream of winning a race against a Formula One car," sighed Mainz coach Thomas Tuchel.
"So it's normal to be overtaken before the end."
A lacklustre first half left Bayern 1-0 down at Munich's Allianz Arena before Goezte came off the bench to play a part in three of his side's goals.
Goetze's superb pass led to Arjen Robben's 50th-minute equaliser before the pair combined to set up Thomas Mueller for the first of his two goals for the European champions.
Croatia striker Mario Mandzukic then converted Goetze's cross before Mueller netted a late penalty in the rout.
Bayern secured their place at the top of the Bundesliga table and extended their unbeaten run to 34 games, just two short of Hamburg's league record set in 1983.
