Carlo Ancelotti said he was "happy with a good performance but not the result" as the Italian tasted defeat for the first time in the Bundesliga, losing 1-0 to Borussia Dortmund in "Der Klassiker" on Saturday.
Gabonese striker Pierre-Emerick Aubameyang's instinctive finish on 11 minutes proved the difference with former Bayern star Mario Gotze providing the assist, nutmegging ex-BVB captain Mats Hummels in the process -- both German internationals playing against their former employer.
"We aren't happy because we lost," Ancelotti told a postmatch news conference. "It was a difficult game. Borussia started well and scored a good goal with a fine combination."
He added: "We tried to make a comeback. After the opening 20 minutes, we started to play well and tried everything, but couldn't equalise.
"Overall, I'm happy with a good performance against a strong team. But of course, the result was not good."
Captain Philipp Lahm was more critical of his side's performance.
"In the first half, we lacked the final decisive pass," he said. "Dortmund had fewer chances than us, but in the end the result tells the story. It ended 1-0 and we've got to live with that."
Lahm was replaced by the Brazilian Rafinha on 68 minutes as the Bavarians chased a leveller.
Commenting on the reasons behind the change, Lahm said: "I wasn't injured. You should ask the trainer. I'm not responsible for substitutions. It doesn't matter whether I was surprised or not."
After their first league defeat of the season, Bayern surrendered top spot in the Bundesliga to Leipzig and now trail the newly promoted side by three points with almost a third of the season played.
Lahm said sarcastically about the new league leaders: "That's nice for the league. Everyone wanted that."
