Hart, 23, is confident he can handle the pressure if Fabio Capello gives him the nod ahead of the more experienced David James and Rob Green.
But handling the official Jabulani ball, named after the isiZulu word for 'be happy', is another matter, particularly after altitude training showed how it will work a few thousand feet above sea level where England play their first game.

Brazil goalkeeper Julio Cesar has already called the ball 'terrible', saying it looks like it comes from a 'grocery store', while Capello said: 'It's terrible for keepers as it's always moving.'
Hart's verdict is succinct.

'They're doing anything but staying in my gloves,' he said with a smile. 'It's hard work with them, but good fun. It makes the game exciting and I think that's what they are trying to do with it.'
And the altitude?
'It's been all right. Obviously it has not been as high and intense as it will be in South Africa. We've had our little gas masks on in the evening, everybody's bought into it and respects that it's going to be different.
'It's just exciting to see. I think we're about 900 metres up where we're training, the air's pretty thin and the balls fly fast. I think there's an awful lot of respect between the keepers.
'Whoever Mr Capello chooses, the other two will be right behind him, myself included. We're a unit, we've got to be behind each other.'
New balls please2010The Jabulani, the official football for the 2010 World Cup, was developed by adidas in conjunction with academics at Loughborough University.
The revolutionary design features eight moulded panels and a 'grip and groove' texture, which is claimed to provide 'unmatched flight characteristics'.
Eleven colours are used on the ball, representing a team's 11 players as well as the 11 official languages of South Africa and the 11 tribes that make up the Rainbow Nation.
