Four days after thrashing Tottenham in Europe, Bayern Munich suffered their first loss of the season on Saturday with a shock 2-1 home defeat by Hoffenheim in the Bundesliga.

Second-half goals by striker Sargis Adamyan sealed a first-ever win at Bayern for Hoffenheim as Niko Kovac's side crashed back down to Earth following Tuesday's 7-2 Champions League rout of Spurs.

"This is a huge dream for me," said Armenian international Adamyan #23, who cost 1.5 million euros (1.6 million U.S. dollars) from second-division Jahn Regensburg in May.

"The win is very important as we have shown that we can beat anyone in the Bundesliga," he added as Hoffenheim won the first time in five games.

It was Bayern's first home league defeat for almost a year.

Robert Lewandowski equalized with his 11th Bundesliga goal this season, scoring for the seventh straight league game before Adamyan clinched the win with his second late on to stun the Allianz Arena.

"We had two simple losses of possession that led to two goals against us – that must not happen," said Kovac.

Bayern captain Manuel Neuer said the defeat served as "a warning you get nothing for free."

Bayern kept first place in the table only on goal difference ahead of RB Leipzig, Freiburg, Schalke 04 and Bayer Leverkusen, with the top five teams on 14 points.

Borussia Dortmund, who made a 2-2 tie with host Freiburg, have drawn their last three league games to drop to seventh.

Likewise on Sunday, both Borussia Monchengladbach, who face mid-table Augsburg, or Wolfsburg, who are home to Union Berlin, could also finish the weekend top.
