England coach Roy Hodgson says his young team needs positive support from fans.
England open their World Cup campaign against Italy.
Hodgson said: "When you are young you need people telling you that you're good. It's not by chance you are doing all these things. If you're so good you can do them for Liverpool in the Premier League, there is nothing to stop you doing them at the World Cup.
"We've only to think back to 1958 and Pele bursting on to the scene as a 17-year-old. He went on to dominate football and become one of the most famous - if not the most famous - footballers of all time. But when he came to Sweden he wasn't even well- known in Brazil. A month later he was a superstar and went on to be an even greater superstar for goodness knows how many years."
