Bayern Munich head coach Thomas Tuchel admitted the Bundesliga title race was over.
The German giants, who won the league last season, lost 2-0 to Borussia Dortmund.
Tuchel knows the result means that his team are now 13 points behind Bayer Leverkusen, who he congratulated on the title.
On the title, he said: Obviously, yes.
"After today's game there is no more need to count points. How many is it now? Congratulations to Leverkusen.
We are very disappointed because we felt we did not bring the necessary passion to win the game.
"It was too little from us when it came to the basics."
On facing Arsenal in the Champions League quarterfinals, Tuchel said: "That is not the first time that it happens to us and it's not the first time we could bounce back with a crazy good performance.
"That is basically the hope. It's a bit strange but that is actually it. If we are honest, we could not have to guarantee that if we perform today at highest level that we do this again at Heidenheim.
"This is our point for many, many months. We struggle to find this consistency. So today we didn't find and now we prepare for Heidenheim.
"We are able to beat Arsenal even if today this is hard to believe. We have very different performances within a short period of time so this is not new to us."
