England face Montenegro and Poland at Wembley later this month, with victory in both matches enough to ensure qualification for the 2014 World Cup.
But Roy Hodgson's men have drawn three of their last five matches.
However, former England captain Beckham, asked if the current side were winners, replied Friday: "I do.
"There's a transitional period that was always going to happen," Beckham said. "You see it throughout sport, you see it throughout teams and countries and obviously Roy Hodgson has come in and done a good job.
"There's players in there that have been in there for many, many years who have experienced World Cups and big games.
"So they have got those players that have got the experience in there, but young players will only learn when they're playing and that's what Roy has done.
"He's brought in a couple of young players that are the future of English football."
Beckham, who retired from competitive football following a short stint with Paris Saint-Germain last season, said: "I think people like to see winners and see teams and the country you support and live in be the best.
"That's why we are a country of believers and there are high expectations in our country.
"Whenever we go into a competition, whether it be football, whether it be any other sport, there's always high expectations and that's rightly so, because we're a country that's passionate about our sport and we're believers and that should never change."
The 38-year-old Beckham was speaking at a Sainsbury's Active Kids event in his native east London.
