The 35-year-old has now issued an apology, admitting he "clearly went too far".
"Emotions are part of sport. And in view of the red card, I had to let off steam after the game. However, I must apologise for my choice of words directed at [referee] Tobias Welz's team. Unfortunately, I clearly went too far," he is quoted as saying by FC Bayern.
A straight red card shown to Dayot Upamecano in the eighth minute made things difficult for the Bavarians.
According to Nagelsmann, Bayern could already have been up by several goals by the time the Frenchman was sent off.
"We could have settled matters before the red card. We had four clear-cut openings. If we're more clinical with those, we go 2-0 or 3-0 up. We started well and created some great openings, but the final ball was lacking," said the Bayern coach.
"Obviously, it was an early red card and made life difficult, but we did well to get back into the game. They went 2-1 up at a point when we were in charge, despite the man disadvantage. It was tough after that - we were also feeling it towards the end after the game in Paris."
