Denmark coach Kasper Hjulmand admitted on Tuesday that “emotions are very, very high” for their must-win World Cup clash against a dogged Australia.
With holders France already qualified for the last 16 from Group D, Australia are in pole position to join them in the knockout rounds with three points from two games.
Going into the final round of Group D games on Wednesday, Denmark are third and Tunisia fourth, both with one point.
Euro 2020 semi-finalists Denmark must beat Australia and hope Tunisia do not do likewise against France if they are to extend their stay in Qatar.
Hjulmand said “everyone is ready” and he has no fitness concerns, but he conceded the pressure is on for a team who had been expected prior to the tournament to progress along with France.
