Bayern Munich was likened to a Formula One car on Saturday, outracing some of the lesser models 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.
