Poland's Robert Lewandowski has not found the net yet at Euro 2016 but Switzerland are aware he remains a major threat when the teams meet in the last 16 of the competition on Saturday.
"It's not like this that a striker who does not score for three games is not good any more," Swiss captain Stephan Lichtsteiner told a news conference Friday.
"He is one of the best strikers in the world for me, he can be problem for us."
Lewandowski was the top scorer in qualifying but has been starved of service at the finals in France. While Poland have not conceded a single goal, they found the net only twice en route to finishing Group C as runners-up.
"We don't have a single problem with the fact Robert hasn't scored a goal," Poland coach Adam Nawalka said. "He's doing a great job for our side."
Switzerland have had their own problems in front of the goal with a similarly meagre two goals to their name in Group A. They finished runners-up behind France having held the hosts to a goalless draw.
"That gives you a lot of confidence, we played a good game against France," Lichtsteiner said. "We played very well, had lot of ball possession against a top side."
Swiss coach Vladimir Petkovic has a full squad available to choose from with no injury or suspension problems.
"We've still got our feet on the ground but we're very excited and would like to continue our progress at the European Championships," he said. "It will be a tough game - once again small margins will decide the result."
Nawalka added that after the group stage - which eliminated only eight of the 24 teams from the tournament - the intensity would increase in the knock-out phase.
"We're very well aware that in the next match only the winner goes through," he said. "The players are aware there's a great chance to get an excellent result here at the Euros."
Croatia or Portugal await the winner in the quarter-finals in the apparently weaker half of the draw which contains not a single side which has won a major honour.
"We know that the gs matches are history and every next match will be like a final for us," midfielder Grzegorz Krychowiak said. "We're aware of the opportunities and possibilities ahead. This side is very ambitious and wants to go as far as possible.
Krychowiak declined to speak about his forthcoming transfer from Sevilla to Paris Saint-Germain, insisting he was "100 per cent prepared for the match."
Unlike Petkovic, Nawalka does have an injury concern over keeper Wojciech Szczesny who missed the last two matches with a thigh injury. Lukasz Fabianski is ready to deputize once more.
