Manchester City's Leroy Sane has said he is unfazed by recent criticism and is focused on improving his game.

Sane was not included in Germany's World Cup squad and played only 30 minutes in the first three Premier League games of the season.

Last month, Germany teammate Toni Kroos criticised Sane's body language, while City boss Pep Guardiola said he would help him to "grow up."

"I love challenges, especially with Pep Guardiola," Sane told Sport 1 following Tuesday's 2-1 Champions League win at Hoffenheim.

"[Germany coach] Jogi Low and Pep Guardiola both know exactly how to deal with me. To receive criticism from big coaches even delights me a bit.

"Criticism is normal in football. I only focus on myself. I want to improve myself. The next goal is to make the next step with the national team and show myself more there."
