France coach Didier Deschamps admitted that the expected scorching heat in Philadelphia during Saturday's match against Paraguay is "not ideal" but didn't want to make a big deal out of it.
"It's not ideal. But I'm not too worried about the heat. Together with the medical staff, we've made sure that various measures have been put in place," the coach said on Friday ahead of the last 16 clash.
The temperature is expected to be above 40 degrees Celsius, which could be an unexpected advantage for underdogs Paraguay.
"The weather is, of course, very similar to what we have in Asunción. Even though we're used to such conditions, this is weather that will undoubtedly influence the game," Paraguay coach Gustavo Alfaro said.
Defender Junior Alonso added: "That's completely normal for us. Hopefully it will get a little warmer tomorrow."
Unlike the arenas in Atlanta or Houston, the stadium in Philadelphia doesn't have a retractable roof. The sweltering heat is also likely to be a real test for the fans.
"We know the weather will be tough. You lose a lot of energy. You sweat more and lose more water. Sometimes your mind isn't as clear. It was already hot when we arrived. Now it's even hotter, but both teams have to deal with it," French forward Désiré Doué said.
High temperatures haven't played a big role in the World Cup so far. Ahead of the tournament, FIFA had already introduced a mantadory hydration break during each half.
Led by superstar Kylian Mbappé, France have had some of the best performances of the tournament so far. The winner of Saturday's clash will face either Canada or Morocco in the quarter-finals.
