(CNN) -- Fabio Capello insists he can lead England to World Cup glory but only if he has a fit squad at his disposal come the start of the tournament in June.
The Italian coach has transformed England after their failure to qualify for the European Championships in 2008 and they now sit among the favorites for football's showpiece event in South Africa.
In an exclusive interview with CNN, Capello said: "I have big confidence in my team. If all the players arrive fit and physically in a good moment we can win the World Cup. We are one of the best teams in the world.
"Sometimes you have to be lucky to beat some teams because there are refereeing mistakes, bad luck, post in, post out, this is football."
One player who has thrived under Capello's leadership is Manchester United striker Wayne Rooney.
The Italian is credited with changing Rooney's style of play to allow him to score more goals, and the evidence of his success is compeling.
The 24-year-old scored nine goals in nine starts during England's qualifying campaign.
"I hope he [Rooney] will be the same in June, not tired, because he is in a fantastic moment," Capello told CNN.
"I told him 'Rooney, if you want to score goals you have to go in front of the goal,' because he work a lot, he run a lot, he help everyone in every moment, he is really generous."
Capello was quick to stress that, as important as Rooney is, it will be very much a team effort if he does lead England to the title.
"He's one of the most important but I think you can not win with only one important player," he added. "If you want to win you have to create a group, a squad, a good system and everyone has to know what he is to do during the game in every moment."
Capello isolated Brazil, Spain and Germany as the main contenders for the World Cup trophy.
"Brazil is a really strong team," he added. "They are good technically, organisation on the pitch is good. Spain play a different style, probably at the moment the best style in the world."
Geoff Hurst scored a hat-trick when England beat West Germany 4-2 to win the World Cup in 1966.
It remains the country's sole success in the tournament to date, but Hurst told CNN under Capello's guidance have a good shot in 2010.
"We've got a good chance this year," he said. "I genuinely believe we're capable of getting to at least the semifinals and from then on it could go either way."
