Germany midfielder Marco Reus has acknowledged that they will be in for a tough game when they face Scotland in their opening Euro 2016 qualifier on Sunday.
The Scots travel to Munich on a six-match undefeated run under Gordon Strachan which has seen them beat the likes of Croatia, Poland and Norway.
"They have not lost for six straight games and they are a strong team with a fighting spirit," Reus told reporters.
Borussia Dortmund star Reus missed Germany's World Cup triumph earlier this summer because of an ankle injury.
