Czech Republic goalkeeper Petr Cech said on Monday despite quarter-final opponents Portugal being viewed as favourites for Thursday's game he believed the Czechs could cause an upset.
"We haven't lost yet, of course you can beat anyone on a good day," said the 30-year-old keeper. "We definitely have a chance to advance. It's sport and anything can happen," he added.
"They are among the world's top ten teams. It's a team full of personalities and outstanding players, and they play very well. Against the Netherlands on Sunday, they were excellent up front," said Cech.
"They also have enough experienced players. The team has matured and it's really strong," he added.
