The Danish Football Association DBU has said the match may be cancelled due to a conflict between the players and DBU.
"The way things look now, Denmark will not be playing the match on Friday," Marika Domanski Lyfors, head of the Swedish National team, told Swedish Radio's sports department.
But Sweden has not given up hope that the match will go ahead.
"We want to believe that things will be sorted out. They can keep it open until 24 hours before the match, and in the end it is UEFA that decides about the match. We want to be prepared in the best way possible, so we are keeping focused and preparing as if the match will happen," she said.
Negotiations between the Danish players and the football association have been ongoing since 2016, and were intenfisied after the team won a silver in the European Cup this summer. The Danish players demand better pay and conditions when they are travelling and training, and they want the same rights as the men's team has. Last month, an agreement still hadn't been reached, and the game they were supposed to play against the Netherlands was cancelled.
A temporary agreement was reached just over 24 hours before the qualifying match against Hungary, which the Danes won by 6-1, but ahead of the match against Sweden, the players have rejected a new temporary solution proposed by the DBU.
If the match on Friday is cancelled, Sweden will be noted as a winner.
