Brighton midfielder Jakub Moder says Poland proved their critics wrong with Saturday's 1-1 draw with Spain.
Robert Lewandowski's second-half equaliser kept alive Poland's chances of qualifying for the knockout rounds.
Moder said: "We've had some luck that we didn't have in previous games.
"I saw a lot of negative comments about us. That we will lose 4-0 or 5-0.
"Virtually every player got hit for the match with Slovakia.
"Within our group, no one doubted and, even when there were some negative moments, we put it out of our heads."
