Robert Lewandowski is positive playing fearlessly is what Poland need to beat Germany in their group C encounter.
Poland emerged victorious in their first match, winning 1-0 over Northern Ireland to claim their first Euro win.
They face Germany and could qualify for the next round, should they emerge victorious.
“It will be a special game against Germany. We know each other very well. We met twice in the qualifiers and Germany are the favourites for me, not just on Thursday but also to win the tournament. They can go all the way,” Lewandowski told Die Welt.
“We know how strong Germany are. But we will fight. Everything is possible in a tournament like this.
“We have to stay calm and act confident. We must play without fear and don’t have any stress. We know it will be hard, but it’s only football and we must enjoy ourselves. We can do it if we approach the game like that.”
