Thomas Müller is fit to play against Japan after recovering from an injury.
"He is definitely an option," Hansi Flick told reporters at today pre-match press conference.
"He did a very good job today in training. We are happy with him. He gives us one more option."
Flick also commented on the absence of Leroy Sané, who is sidelined with a knee injury.
"It's bitter that we have to do without Leroy. He can decide a game with his quality alone. We hope he can play on Sunday."
