England goalkeeper Joe Hart insists the intense heat in Brazil will not be blamed for any poor performances at the World Cup.
Roy Hodgson's side face a tough test of their fitness in the Amazonian city of Manaus when they take on Italy in their opening fixture on June 14.
Hodgson will ready his squad with training camps in Portugal and Miami, and Hart is confident the players should be fully acclimatised by the time they arrive in Brazil.
"It's going to be hot out there, we're just going to have to deal with it," said the Manchester City keeper during a Q&A with fans on England's Facebook page.
"No excuses when we're out there, it's only weather."
Hart also claimed his focus was now completely on the World Cup after he helped City clinch their second Premier League title in three seasons last weekend.
"The Premier League thing finished last Monday after the victory parade," he said.
"It's on to the World Cup now. I'm an England player, part of a really good squad with some great talent, that's what's going to give me belief in the tournament."
Asked if England can go all the way in Brazil, he added: "Why not? We are all winners.
"I am going to go there with my attitude to try and win every game and if you win every game you win the World Cup. You can't go in accepting failure or defeat."
Hodgson's side face a tough battle merely to escape their group after being drawn against Italy, Luis Suarez's Uruguay and Costa Rica.
Hart's fellow goalkeeper Fraser Forster said: "Italy and Uruguay are going to be very tough, but all the games in the group will be hard. With the climate as well it's not straightforward."
The England squad, including injury doubt Phil Jones, will head to Portugal on Monday.
