Dayot Upamecano's performance in Sunday's 2-1 Bundesliga defeat to Eintracht Frankfurt was defended by Bayern Munich head coach Julian Nagelsmann.
Eintracht Frankfurt ended a run of 30 games without losing at home when Martin Hinteregger and Filip Kostic scored at Allianz Arena to stun the Bundesliga champions and leaders.
Upamecano was chastised after his performance, with the off-season signing from RB Leipzig being penalized for surrendering control as Kostic scored the game-winning goal in the 83rd minute.
Asked about France international center-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 counterattacks. 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 Munich have been in phenomenal form entering into this encounter against Eintracht, whom they had beaten in 12 consecutive home league matches prior to the visit on Sunday.
The Germany giants, who last lost in the German top league on home soil against Bayer Leverkusen 31 games ago, are currently level on points with the latter heading into the international break.
