England captain John Terry believes their early qualification for the World Cup will give the Three Lions an advantage over most of their rivals.
England ensured their place in South Africa next summer with Wednesday's 5-1 demolition of Croatia, which maintained their 100 per cent qualifying record.
Coach Fabio Capello still has two qualifying games remaining to tinker with his side and tactics and Terry believes that could be key when England come up against stern opposition next summer.
"Qualifying early is a huge boost for us," said the Chelsea defender. "We then give ourselves an awful lot of time where the manager can try different formations and different players for the World Cup.
"It will be perfect for the manager to maybe go ahead and try players that maybe deserve their chance."
Terry also believes that a return of the players' confidence has been behind Capello's successful rehabilitation of an England side he inherited following the failure to qualify for Euro 2008.
"Fabio has brought a lot of stability. When he came in, we were at a low point in our careers and as a nation collectively," he continued.
"He has installed a lot of confidence. He has come in from day one and told us exactly how he wants to play. He has believed in us.
"To have a manager to come in and believe in us so much - after what happened before - has given us the confidence and trust in him and his formations, the players he selects, and the training he does."
