Portugal ready to oust Netherlands
Portugal coach Paulo Bento hold the aces to eliminate the Netherlands
The Seleccao das Quinas have been far from impressive at the tournament and needed a Silvestre Varela goal to edge Denmark 3-2.
Portugal are seeking a fifth successive UEFA European Championship quarter-final spot.
Paulo Bento's side will progress with victory unless Denmark win by a one-goal margin other than 2-1 and 1-0 in the other match against Germany.
They will go through with a draw unless Denmark win.
Portugal will also qualify if they lose by a one-goal margin and Denmark are beaten.
Bento will field the same XI against the Netherlands tomorrow night in Kharkiv. In fact, it will be a line-up that is beginning its fifth successive competitive match unchanged, having started in both legs of the emphatic qualifying play-off win against Bosnia-Herzegovina.
Midfielders like Miguel Veloso and Joao Moutinho can control the tempo with their passing, and players from all sectors of the team, such as Fabio Coentrao and Cristiano Ronaldo, can switch the play from defence to attack at great speed.
Netherlands are nervous ahead of their must-win clash after suffering two consecutive defeats in Poland and Ukraine.
But victory by more than one goal alone will not be enough to see them go through, as Germany must also defeat Denmark.
Should they go through, they would be the first team to qualify from the group stage with three points since 1992, when it was still two points for a win.
Netherlands coach Bert van Marwijk confirmed he would make changes to his starting line-up with Klaas-Jan Huntelaar Huntelaar strongly tipped to start.
He has also spoken of his team's defensive frailties and the "uncertainty in the players' heads".
