This tends to be a really entertaining fixture, the most recent meeting between the sides back in April produced seven goals as Bayern ran out 4-3 winners with both sides posting a healthy xG (2.69-2.21).
Each of the last 18 (!) head to head meetings between these sides has seen 3+ goals, stretching all the way back to 2018. You can’t use that alone to justify a bet, but it’s a very notable trend that is likely to continue here when looking at the records of both of these sides.
Bayern are seeing 4.38 goals per game in the Bundesliga this season, scoring most of those goals themselves. They’ve seen 3+ goals in 88% of their matches, also seeing BTTS in 75% of their games.
Mainz aren’t too far behind this total, they’re seeing 4.25 goals per game and have seen this selection land in three of their four home matches.
