Chelsea defender Gary Cahill says England go into their World Cup opener with Italy on the back of a perfect preparation.
England's opening match against Italy on Saturday is taking place in the humidity of the Amazonian city Manaus, and the Three Lions have trained in the Algarve, Miami and Rio to try to acclimatise to the conditions.
Cahill said: "I don't really know what to expect. 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.
"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.
"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."
