Bayern Munich head coach Julian Nagelsmann defended Dayot Upamecano's performance in Sunday's 2-1 Bundesliga upset at the hands of Eintracht Frankfurt.

A run of 30 matches without defeat at home was snapped by Eintracht, who stunned the Bundesliga champions and leaders thanks to Martin Hinteregger and Filip Kostic at Allianz Arena.

Upamecano was criticised following his display, with the off-season recruit from RB Leipzig punished for losing possession as Kostic scored the 83rd-minute winner.

Asked about France international centre-back Upamecano, Nagelsmann told reporters: "I didn't have a conversation with Dayot Upamecano yet. After the game, there is sadly no time for me.

"The whole chain, has done a lot of steps forward in the recent weeks. They have done it better before though. They were all not so clear with their actions.

"That's why the opponent had that many counter attacks. Kostic has done it very hard for us today and has scored the goal in that duel.

"Upa has played a lot of good games since he is here and today a weaker one. That can happen."

Bayern had been in scintillating form heading into this match against Eintracht, whom they had beaten in 12 successive home league matches prior to Sunday's visit.

Nagelsmann's Bayern, who last tasted defeat on home soil in the German top flight against Bayer Leverkusen some 31 games ago, are now level with the latter atop the summit heading into the international break.

"First of all, congratulations Oliver [Glasner] and your team," Nagelsmann said after Leon Goretzka's 29th-minute opener was cancelled out within three minutes. "I think this was a game, which we didn't need to lose. It started to look like this in the second half, where we did not have a good structure anymore. This game wasn't a lot different, from the games before, just the result was.

"We did have a lot of chances today and unlike in [Dynamo] Kiev and Bochum, we just didn't score the goals. We only scored one, which could have been enough. Despite that, the game was very similar. Now it is the international break and we will have some time afterwards to go over those scenarios. There is a lot to take out of the last three games, where we could have done similar things better, want to make better and will do better. In the end, there were two very dangerous counter attacks. Once we had a lot of luck, that Frankfurt did not pass the ball deeper earlier, to then go 2-0 ahead.

"Instead Manuel [Neuer] was able to get the ball. With the goal we conceded, we had a feeling in the second half. [Djibril] Sow had a lot of time on the ball and dribbled four metres sideways. That was most of the time like this. Very rarely, Frankfurt had the pressure to pass the ball into the depth. Instead, they had a lot of time in their actions. That cost us the true pressure-phase in the second half.

"We weren't able to build up the pressure, from a secured defence. In nine out of 10 situations, we got out of our box. We had to run then back into that deep block, then one counter, we couldn't get and that went in. Whether we deserved it or not, we had 20 shots on target to their five and it doesn't matter if it was deserved. We lost. Frankfurt did well and we could have done a lot of things better to win. It is like this now, that's why I will still continue and we will look forward to the game against Leverkusen after the international break."
