Germany international Marcel Schmelzer has warned his colleagues that Austria will not be pushovers in Tuesday's World Cup qualifier in Vienna.
The Borussia Dortmund defender feels the Austrians have a lot of quality in their ranks, and could pose a stern test for the Nationalelf.
"Austria are a very unpleasant team to face," Schmelzer was quoted as saying on the official DFB website.
"They are a tough opponent, especially when you take them on in Vienna, and in particular in front of 60,000 home fans at the Ernst Happel Stadium.
"Austria have developed into a strong footballing nation again. Eight players from their current team ply their trade in the Bundesliga and are regular starters at their respective clubs. That says a lot about the quality they have in their team."
Tuesday's encounter is scheduled to kick off at 20:30CET.
