Joe Hart insists he has the mental fortitude to cope with being England's number one at a World Cup.
England have had some fine goalkeepers in recent times, but many of them will always be remembered for the sloppy goals they let in on the international stage.
David Seaman won 75 caps, but he will always be remembered for letting in Ronaldhino's speculative long-range lob at the 2002 World Cup, while Scott Carson was blamed for England's failure to qualify for Euro 2008 thanks to his gaffe against Croatia.
David James could never escape his 'Calamity James' moniker despite 13 years' international service, and Rob Green allowed a Clint Dempsey strike from outside the area to squirm through his hands and over the line to gift the United States an equaliser in South Africa four years ago.
If you don't (have mental strength), there's a good chance you'll get trampled to the wayside.

For Carson, Green and Seaman, their gaffes proved terminal. They barely played for England again.
Hart was sat on the bench that day in Rustenburg and he knows the same could happen to him at the World Cup in Brazil.
"He had a bad moment, which we all have," the England goalkeeper said.
"That's the nature of being a goalkeeper. Robert understands that, I understand it.
Hart may have not let in a howler for England yet, but he has made a few big mistakes for Manchester City in the 2013/14 season - notably against Bayern Munich, Chelsea and Aston Villa.
He lost his place in the City side, but he never lost faith in his own abilities and won his spot back two months later before putting in a number of sterling displays to help his team win the Barclays Premier League.
"Goalkeeper is a position that requires (mental strength)," Hart added.
"And if you don't (have it), there's a good chance you'll get trampled to the wayside. It's a position where you need to be strong and focused."
Although City manager Manuel Pellegrini decided to take Hart out of the firing line last autumn, England coach Roy Hodgson never considered taking such a step.
Hodgson started Hart against Germany in November and he has played in all but one of the England friendlies that have followed.
Barring illness or injury, the 27-year-old will start the Three Lions' World Cup opener against Italy on Saturday in the sweltering heat of Manaus, where England landed on Thursday after a three-and-a-half-hour flight from Rio.
Ben Foster and Fraser Forster are a long way behind Hart in terms of quality and experience, but he believes he cannot afford to take the World Cup lightly.
"I haven't 'come through it and now everything's fine'," Hard said. "I've got to keep working hard.
"City can potentially (buy) whoever they want and I totally understand that, so I need to be at that level to keep my place.
"And I'm playing for England, one of the greatest nations in football history."
