Andre Schurrle bagged a brace as Borussia Dortmund swept away Sandhausen 3-0 in a friendly on Monday.
The match, which celebrated the second-tier club's centenary, saw its first goal just eight minutes in, when the Germany international guided home Raphael Guerreiro's low cross at the near post.
Dortmund, coming off a 2-0 defeat to Bayern Munich in the German Super Cup on Sunday, went 2-0 up seven minutes after the break thanks to help from an error by Sandhausen's Rick Wulle -- the goalkeeper passing straight to Emre Mor before the 19-year-old winger fired into a gaping net.
Dortmund then completed their comfortable victory seven minutes later, with Schurrle collecting a Mor pass behind the defence and lobbing a helpless Wulle.
In other friendly action, Hamburg toppled Danish side Lyngby 3-1 in Rendsburg, Germany.
Aaron Hunt, Gideon Jung and Pierre-Michel Lasogga scored for the Germans after Casper Hoejer Nielsen had put the Copenhagen club in front after just nine minutes.
