I just watched the first half. It wasn't great but not disaster level like some people suggested. I wouldn't say the whole team sucked, it was really half the team. Peru was poor as well.
The heat obviously played a role (especially after 20mins) - and impacted a couple players more than others who were hanging on for dear life. The pressing gassed them, there is no doubt. By the 25th minute, it was like we were playing with 7 outfield players.
Koné really never got going, so I don't think heat was his issue. Even in the first 5mins, he looked slower than everyone (in movement and thought).
FWIY - There were 2 water breaks and both desperately needed. One triggered by Crépeau going down (à la Borjan) before a Peru corner.
