Poland are one of only two teams left, with Germany, who have not yet conceded a goal. But they will need star striker Robert Lewandowski to start firing against Switzerland.
The 27-year-old Bayern Munich star was the top scorer in Euro 2016 qualifiers with 13 goals. But he has yet to open his account at the finals in France.
Polish fans are nervous, even if coach Adam Nawalka said there is no problem with Lewandowski's play. "He is doing a great job for our side and is an important part of the team."
Switzerland are also having attacking problems of their own, having scored only twice so far. Their head coach Vladimir Petkovic said: "We need to focus on the killer pass and killer cross to players inside the box."
The game on Saturday will see two teams who have looked solid at the back, but rather tame in attack go head-to-head. Which team will have a bit of bite to their attack and progress?
