Only 20,000 tickets have been sold for Bastian Schweinsteiger's Germany farewell against Finland at the Borussia Park in Monchengladbach on Wednesday.
Schweinsteiger, 32, is set to win his 121st and last cap for Germany in the 2014 World Cup winners' friendly against Finland.
However, the Manchester United midfielder is not likely to play in front of a capacity crowd as 20,000 of a total of 44,000 available tickets have been sold, a DFB spokesperson confirmed on Tuesday.
"I am looking forward to every single supporter showing up," Schweinsteiger said at a news conference.
Ticket prices at the Borussia Park range between €22 for the cheapest seats and €75 for the highest category.
