The Portuguese face a familiar foe in Denmark on Wednesday evening. The two were drawn together in the qualifiers for both the World Cup and the European Championships and will walk out at Lviv knowing that only a win will keep them booking early flights home from Poland and Ukraine.
Denmark: The Danes pulled off the shock of the tournament so far when they defeated 2010 World Cup finalists Holland on Saturday to go top of Group B and will be full of confidence and resolve going into this fixture. They will be boosted no end by the fact that if they do win they will become the first team to qualify for the knock-out stages.
Coach Morten Olsen has no injury concerns and is likely to name the same starting line-up that beat the Dutch 1-0. Should he opt for a change, however, it could be to recall utility man Michael Silberbauer, who brilliantly marked Cristiano Ronaldo in their home win in the qualifiers last year.
Portugal: After suffering defeat at the hands Germany on Saturday, the pressure is on Paulo Bento's side to deliver. They realise there is no margin for further errors in the Group of Death and a loss to Denmark would eliminate them from the tournament with a game to spare.
Besiktas striker Hugo Almeida has recovered from illness and should replace Helder Postiga, following the Real Zaragoza forward's unimpressive performance against the Germans. Bento also has winger Ricardo Quaresma available for selection after the former Chelsea and Inter Milan player recovered from a leg muscle issue.
