The German FA (DFB) has confirmed there are still thousands of unsold tickets for Germany's Euro 2016 qualifier against Republic of Ireland on Tuesday.
Germany will be looking to get back to winning ways at Schalke's Veltins-Arena following the shock 2-0 defeat to Poland on Saturday but a DFB spokesperson said that, 24 hours before the Ireland game, there were approximately 4,000 tickets still available.
The stadium in Gelsenkirchen has a capacity of 54,442 for international matches.
"Maybe it's more interesting for the Schalke fans to watch Roberto Di Matteo's training sessions," Germany and Schalke midfielder Julian Draxler told a news conference ahead of the match.
Germany also failed to sell out their last qualifier, against Scotland in September, with around 60,000 fans turning up at Dortmund's Westfalenstadion, which can house 65,590 supporters during international matches.
Draxler added: "We'll be happy if it does sell out, and if doesn't then we have to put in a performance so that we'll sold out the next match."
Draxler came off the bench in Germany's 2-0 defeat in Poland after nursing a cold the week before, but the midfielder believes he will be fit to start against Ireland.
"Should the Bundestrainer ask me whether I can play, I'd signal that I'm ready," the 20-year-old said.
Joachim Low, who will be without Christoph Kramer due to a cold, told the news conference that he will start Bayer Leverkusen's Karim Bellarabi, who made his debut against Poland, along with full-backs Antonio Rudiger and Erik Durm.
Low, who rued Germany's failure to take their chances on Saturday, said: "We can expect a copy of the Poland match.
"Ireland are extremely powerful, and they have similar players to Poland. [Robbie] Keane, with his huge experience upfront, and wingers like [Aiden] McGeady can always cause danger. They have six points now, and have justified hopes of making it to France."
