But the response they got from the giants was devastating as Bayern smashed in six goals, beginning with Benjamin Pavard’s equaliser. Then David Alaba scored a superb free-kick, before the break.

Ivan Perisic increased Bayern’s lead nine minutes into the second half. Kingsley Coman, Robert Lewandowski and Alphonso Davies all added to Mainz’s misery.

Mainz were thrashed 6-0 in the corresponding fixture last season.

All of Bayern’s five Bundesliga goals heading into Saturday’s contest had been scored by Lewandowski, but the champions’ back-up brigade came to the fore this time around.
