Denmark's involvement in the new Nations League, including their proposed meeting with Ireland in Dublin next month, has been thrown into doubt in a bitter row between the Danish players and their football association.
And already, Wales defender James Chester has welcomed the possibility that their Nations League could be without Christian Eriksen and company in Aarhus on Sunday, with the possibility that the Danes may field a second-string made up of home-based players.
The Danes are involved in an extraordinary row between their Player Association (Spillerne) and Football Association (DBU) which threatens both this fixture and Denmark's participation in the 2020 European Championships.
The long-running dispute is over a new commercial rights agreement for the players, while the DBU claim that meeting the players' demands for improvement on travel and accommodation has come with a financial cost to the DBU which has forced them to make cuts in other areas of the game in Denmark.
"It would certainly make it an easier fixture without Eriksen," Wales man Chester said. "He is one of the best players in the Premier League. He showed that at the World Cup."
Denmark are due to play a friendly in Slovakia tomorrow but at present do not have a playing squad to fulfil the fixture.
Manager Age Hareide and assistant Jon Dahl Tomasson are said to be "working from home" and will not be in charge.
Denmark have already been warned they could be banned from UEFA tournaments after their women's side boycotted a World Cup qualifier last year in a dispute over employment conditions.
"All is not well over there at the moment, but it's nothing to do with us," Chester said.
"We'll be in Denmark on Sunday regardless of what squad they pick, and looking to win the game whoever's playing."
