Bayern Munich winger Leroy Sane says he has been unfairly put in the "bling-bling drawer" and will take criticism as an incentive to realise his potential.
Sane was unable to hit the ground running at Bayern after joining the European champions on a five-year deal from Manchester City in July for a fee of €49million, which could rise to €60m.
The winger missed almost the entire 2019-20 season with City due to a torn anterior cruciate ligament before returning to his homeland.
Bayern chairman Karl-Heinz Rummenigge last month warned Sane must show more desire and says Bayern will be prepared to "kick his butt" if needed to get the best out of their big-money signing.
Sane has since taken his goal tally to seven for the season, while also providing five assists in 21 games, and Rummenigge this week rubbished suggestions the Bundesliga leaders could sell the 25-year-old this year.
Bayern and Germany great Lothar Matthaus stated the Bavarian giants should have signed Timo Werner rather than Sane before the Germany forward moved to Chelsea.
Sane insists people have got the wrong impression of him.
"You are welcome to come to my house and see if there are really diamonds, gold chains and stuff like that lying around. I don't own any of these. Still, people put me in this bling-bling drawer." he said in an interview with Der Spiegel.
He added: "I have the feeling that people look at me differently than others. Apparently I provide people with material like this, even though I don't want to. So of course I have to question myself."
Sane took note of Rummenigge's criticism and has vowed to repay the faith Bayern have shown in him.
"I'm working very hard to get there [back to his best]." the former Schalke man said. "I just have to really prove myself at Bayern.
"I know that the club is behind me, otherwise they wouldn't have taken me. I also take this criticism as an incentive."
Sane also said he has no problem with Germany coach Joachim Low after he was overlooked for the 2018 World Cup in Russia, although he described the snub as a "hard blow" to take.
"The national coach had his reasons and I always had a good relationship with him. After the World Cup he came to me and said that I should continue like this. That he believes in me. That was the end of the topic for me." Sane added.
