Roy Hodgson believes the location of England's 2014 World Cup group games, rather than the opponents, will prove the biggest factor in whether or not they progress in the tournament.
Speaking at an FA-backed 'Just Play' training session near Wembley, Hodgson said he is keen to avoid playing in the Brazilian tropical northern cities of Manaus and Fortaleza.
The England manager will learn when and where England's group stage matches will be played when the draw takes place on Friday in Salvador, Brazil.
Unseeded England are already guaranteed to face one of the teams in the top pot of seeds which includes Brazil, Spain, Germany and Argentina.
Hodgson told Sky Sports News: "We will go to Brazil believing that whatever group we get we are capable of getting out of it.
"We are in the right place as a hub, we were one or two of the teams that could choose our base in Rio which we thought was very good. It will depend on where we are drawn but for most circumstances, Rio is pretty good.
"Before the draw, what preoccupies me the most is where we are going to be drawn because that will have an effect on the Northern European teams.
"If there is any good luck going, I hope it will be in relation to where we are due to play because whatever group we get is going to be a tough group.
"The north of the country is where we believe the weather is a major factor because it becomes more tropical, in particular the Amazon rain forest up in Manau.
"That's pretty obvious that the weather is difficult for any team to deal with and not just the European teams, and a place like Fortaleza - the climate will be tough.
"We said the same about South Africa, but basically you play where you are drawn to play and whatever happens, we will have to make sure our preparations are right and just get on with it."
