Pearce was an animated presence as his side collapsed to a four-goal reverse with UEFA president Michel Platini among those said to have been left unimpressed.
There have even been claims that Pearce might have caused damage to England's bid to host the 2018 World Cup.
Pearce: "You can't win.
"It's quite comical really. When it suited, Sven-Goran Eriksson was so calm and relaxed on the touchline. At the time people said it was fantastic.
"Two years later, the same people said he lacked passion.
"Possibly I could have been criticised for being a bit over zealous on the touchline but I will learn from that.
"If some people say I need to calm down my attitude then the only thing I would say is that I am very passionate about England winning.
"It is a big drive for me to be successful with my country.
"I will do everything I possibly can to make sure we win but if people think I was out of order, I will apologise.
"Anyone is up for criticism. The German team were celebrating by having a water fight five minutes before the end of the match.
"If I had done that with my coaches, I would have been criticised.
"I am in the glare of the media the whole time and if people say I have to calm down on the touchline I will do. If they don't say anything I won't.
"The one thing that underlines everything is that I am desperate for the team to do well and I want to motivate them."
