Gary Cahill insists the England team has prepared well for their opening World Cup fixture on Saturday.
The Three Lions take on Italy at the Arena Amazonia in Manus in what is expected to be extremely hot conditions, four hours on a plane from their base in Rio de Janeiro.
Chelsea centre-back Cahill, who is likely to start for England on the weekend, says the squad has done everything they can to accustom themselves with the heat and humidity and hopes the players are able to get through their important first match against the Azzurri.
"I don't really know what to expect," he said. "I have been told, obviously, about the humidity.
"That was the first thing we were all made aware of, but that's what we've been training for and preparing for in the last couple of weeks. That was the main thing really.
"I think we've prepared the best we possibly could in the couple of weeks we had.
"We did the hot-weather training, been in hot climates, done the heat chambers, worn extra layers of clothing.
"So we've prepared as best we possibly could. Obviously being English players we're not used to those conditions but in the three weeks that we've had we have done all we possibly can."
