Can has only made three substitute Serie A appearances for Juventus after being left out of the club's Champions League squad this season.
The 25-year-old midfielder was a 71st-minute substitute against Inter last week, taking his tally to just 78 league minutes in 2019-20 under head coach Maurizio Sarri.
Can did manage to complete the full match in Germany's 2-2 friendly draw with Argentina on Wednesday and he told reporters: "I'm not happy [at Juventus] right now. I don't play much at the moment.
"Last season I played a lot. Especially in important games for Juventus. And I also played well there.
"I haven't had a chance this season. But now I think, when I come back to the club, I will get chances again.
"I am definitely grateful to Joachim Low. Because I didn't play much in the club and he invited me anyway.
"Nevertheless, he gave me the chance. That's why I was simply happy that I played again."
Can and Germany are back in action on Sunday, when they travel to Estonia for their Euro 2020 qualifier.
