Germany's World Cup players in Bayern could boycott the friendly against Denmark on August 11, the club coach Van Gaal said in a press conference on Thursday.

"They return from holiday on August 2 and then they must leave for an friendly on August 9. It is nonsense," van Gaal said.

The Bayern coach added: "If eight Bayern players decline to play at the friendly then I think the DFB (German Football Association) would listen to the clubs issues."

DFB General secretary Wolfgang Niersbach counterattacks Louis van Gaal criticism in an announcement: "Of course, cancelling of the friendly against Denmark is not an option."

Champions Bayern Munich will face Wolfsburg at the Bundesliga opener on August 20.
