Poland has struggled in European Championship qualifying and faces Portugal on Wednesday with winger Cristiano Ronaldo in top form.
With four points from three games, the Poles want at least a draw.
Portugal, on four points from two games, hasn't lost on the road in international qualifying for 10 years.
``Of course we're going there looking for a win, even though we know Poland is a tough outfit,'' said Ronaldo, who scored two goals in Portugal's 3-0 weekend win over Azerbaijan.
The Manchester United winger _ with 14 goals in 41 games _ has taken over the playmaker role left by retired Luis Figo.
Portugal coach Luiz Felipe Scolari looks set to replace Atletico Madrid midfielder Maniche with Armando Petit.
Sporting Lisbon's 19-year-old standout winger Nani is also challenging for a place in the starting lineup, though he's unlikely to push out the more experienced Benfica midfielder Simao Sabrosa.
With striker Helder Postiga in doubt due to a knee strain, Nuno Gomes should keep his place up front despite a lacklustre performance against Azerbaijan.
New Poland coach Leo Beenhakker also is wrestling with injury problems and inconsistent play.
Winger Euzebiusz Smolarek, who plays for Borussia Dortmund, was the sole bright spot on a Polish squad plagued by errant shooting and sloppy passing in its 1-0 win at Kazakhstan on Saturday.
``We have to do better to take advantage of our scoring opportunities. If we have at least six or seven good chances, we have to score three or four goals,'' striker Maciej Zurawski said.
``Every team is beatable and Portugal has its weak points too.''
Poland is still settling into Beenhakker's new style of play, but injuries have also taken a toll.
Central defender Mariusz Jop withdrew from the squad last week with a twisted knee, while forward Ireneusz Jelen and defender Arkadiusz Glowacki are both out with leg injuries.
Veteran midfielder Jacek Krzynowek could be back in the lineup after missing the Kazakhstan match with a sore back.
Serbia leads Group A on seven points, two ahead of Finland and three points clear of Portugal, Poland and Belgium on four.
Portugal was runner-up to Greece at Euro 2004 and fourth at the World Cup in Germany.
