At the ripe old age of 40, captain Cristiano Ronaldo has been included and is set to earn his 218th international cap up front, while Martinez has a plethora of other attacking options at his disposal.
Indeed, Rafael Leao and Pedro Neto are arguably the two most likely candidates to join Ronaldo in a front three, although they face competition from Joao Felix, Diogo Jota, Goncalo Ramos and Francisco Trincao.
Meanwhile, 17-year-old winger Geovany Quenda, who has reportedly agreed to join Chelsea from Sporting Lisbon, has been handed his first senior call-up and could make his debut in some capacity on Thursday.
Bruno Fernandes served a one-match ban when Portugal played out a 1-1 draw with Croatia in their last match in November, but the Manchester United man is available to return against Denmark and should start in midfield alongside Paris Saint-Germain duo Vitinha and Joao Neves.
While Diogo Dalot and Nuno Mendes operate as full-backs Ruben Dias could be partnered at the heart of defence by either Antonio Silva or Goncalo Inacio, protecting goalkeeper Diogo Costa.
Portugal possible starting lineup: Costa; Dalot, A. Silva, Dias, Mendes; Vitinha, Neves; Neto, Fernandes, Leao; Ronaldo
