The league leaders suffered their second loss this season, which could cost them top spot if second-placed Leipzig beat Dortmund Saturday
Bayern Munich head coach Hansi Flick admitted it was errors by the European champions which cost them a 3-2 Bundesliga defeat at Borussia Moenchengladbach Friday.
The league leaders suffered only their second loss this season, which could cost them top spot if second-placed RB Leipzig beat Borussia Dortmund at home Saturday.
Bayern were cruising at 2-0 up after 26 minutes thanks to a Robert Lewandowski penalty and a superb Leon Goretzka goal at Borussia Park.
However, Gladbach roared back as midfielder Jonas Hofmann scored twice to make it 2-2 at the break, then set up Florian Neuhaus who scored what proved to be the winner for the hosts just after the break.

Thomas Mueller agreed with Flick that Bayern can only blame themselves.
In the pre-match build-up, Gladbach coach Marco Rose had highlighted Bayern's tendency to defend high up the pitch, which created space for opponents to attack, and his team ruthlessly exploited the weakness.
Rose's side still trail Bayern by nine points in seventh place.
