Owing to a dispute with the players' union regarding the commercial rights of the players, the Danish Football Union named an entirely uncapped squad, consisting of a mixture of futsal players and players from the Danish 2nd Division and the Denmark Series (the third and fourth tier of Danish football respectively), in lieu of the regular side, to face Slovakia in a pre-Nations League friendly, and it was feared that the same squad would be used for the competitive fixture against Wales. The dispute arose due to the image rights of the players, with Hummel having the exclusive right to the manufacture and marketing of Danish kits. The DBU wanted to use individual players, without explicit permissions, in their advertising. Hareide would similarly not be involved, with the side instead falling under the temporary management of John Jensen, with Hasse Kuhn serving as the assistant manager. The Danish FA are currently under a four-year probationary period with UEFA for having forfeited a Women's World Cup qualification game against Sweden in 2017 due to a similar dispute with the women's team, and a further violation could have resulted in Denmark being prohibited from participation in either the 2018–19 UEFA Nations League or the 2020 European Championship. After a temporary agreement enabled the return of the regular players, the Danes won their first Nations League fixture 2–0.
