A commercial disaster sees Jensen fill in
squad, including players from third-tier club Avarta, fourth-tier Vanlose and the Jaegersborg four who played in the 2016 Futsal World Cup.
The DBU confirmed 53-year-old Jensen will be in charge of the Slovakia and Wales games rather than national team coach Age Hareide.
“Where we are now, I see only losers in the conflict, and Danish football loses most of all,” said Jensen.
“When I say yes to help here, it’s because I feel very strongly for the national team as an institution, and because I think the most important thing must be that the games will be played.”
Jensen, who scored in Denmark’s 1992 European final victory over Germany, spent eight months coaching in the Premier League at Blackburn back in 2011.
He went on to become a consultant at Brondby and spent four years in charge of Danish club Fremad Amager between 2014 and 2018.
“I do not consider the matter between DBU and the players, my ‘yes’ is not an expression of it,” said Jensen.
“I just hope to help us get through the two matches and that the parties find a solution as soon as possible.
“The national team has meant infinitely much to me in my career and in my life.
“It hurts to follow this course, and I hope my contribution can help mitigate the negative consequences.”
Denmark, who reached the last-16 of the World Cup in Russia this summer and are ninth in the FIFA rankings, have been beset by internal problems over the past 12 months.
The women’s team boycotted a World Cup qualifier against Sweden last October in a dispute over employment conditions.
Sweden were awarded a 3-0 win and UEFA fined the DBU £18,000, and also warned that Denmark would be barred from UEFA tournaments if they cancelled another match in the next four years.
So failing to play Gareth Bale’s Wales would almost certainly see Denmark expelled from Euro 2020.
DBU elite manager Kim Hallberg said: “We must field teams in the two matches to avoid millions in fines and possible exclusion of the national team for several years.”
