The German champions have now conceded the first goal in their last eight matches.
It is a worrying trend for Hansi Flick’s side, their defense has been at sea far too often this season and those problems yet again were on show in their 5-2 win over Mainz.
Despite the scoreline, which paints a picture of a dominating victory, Mainz more than had their fair share of chances to pile on the pressure.
Throughout the first half, Mainz seemingly could get at Bayern whenever they please, with Jonathan Burkardt at the heart of it. With Burkardt’s well-taken goal, even though there was a hint of a foul on Jerome Boateng, Bayern again fell behind and it is becoming a worrying theme for the German champions.
Mainz went into the half time break 2-0 up thanks to an Alexander Hack header and the game could have taken on a different complexion had Danny Latza put his shot either side of Manuel Neuer in Bayern’s goal to put his side three goals up just minutes into the second half and in truth he should have.
However, that is how football goes sometimes and Bayern’s attacking prowess overwhelmed Mainz as they eventually ran out comfortable winners in the end.
Speaking to Sky Sports, Joshua Kimmich said they must start games better instead of always playing from behind and that it was clear Mainz had a game plan to close the centre of the pitch.
“Of course it’s exhausting when you’re always behind,”
“We want to win games more easily again, it takes too much energy that way.”
“You noticed that Mainz wanted to close the center.
“We went in with a completely different attitude in the second half. In the first half, Mainz were clearly ahead of us and really hurt us. We were lucky that they didn’t make it 3-0.”
It is certainly a cause for concern despite Bayern sitting top of the Bundesliga, two points clear of RB Leipzig in second.
If they can fix up their defensive issues then that spells trouble for the rest of the league, if not, then the title race could go down to the wire.
