Germany goalkeeper Manuel Neuer has warned his side about the danger that Robert Lewandowski will pose when the world champions meet Poland on Saturday.
"Lewandowski is one of the world's best strikers," Neuer told reporters.
"We will have to be careful. It's important to kick on from our three points against Scotland, but it will be a tough game in Warsaw."
Lewandowski has scored four goals for the Bundesliga champions since his move from domestic rivals Borussia Dortmund in the summer.
