He added: "It is very dangerous. Many people think we are already in the World Cup. We have to play a good 90 minutes tomorrow to be there.
"Qualifying for the World Cup Finals would be one of the biggest things that has happened to me. Beating Greece tomorrow will be one big step towards something beautiful, because, if we qualify, I think we can do well next summer."
England's players will have their names on the back of their shirts tomorrow for the first time other than during a tournament final.
The players have been pushing for names to be printed as well as the numbers and their wish will be granted.
The name 'Fowler' will be on one of those shirts.
Fowler, who has had his problems at club level so far this season, has been given the task of replacing club-mate Michael Owen.
Arsenal defender Martin Keown, as expected, replaces injured clubmate Sol Campbell, and will partner Rio Ferdinand at the heart of England's defence.
Leeds' former Crystal Palace goalkeeper Nigel Martyn comes in for Arsenal's David Seaman, who has a shoulder injury.
In midfield, Gerrard plays alongside Liverpool team-mate Nick Barmby and the Manchester United pairing of Paul Scholes and skipper David Beckham.
Beckham will also wear a stars and stripes armband in honour of the victims of the terrorist attacks in America.
Manchester United's Nicky Butt withdrew from the squad today after failing to recover from a rib injury.
