David Beckham
Born: 02/05/75
Position: Midfielder
Club: Real Madrid
Caps: 66
Goals: 13
Beckham has been in good form for Real Madrid - encouraging news with Euro 2004 just weeks away.
Doubts whether he would succeed in Spain quickly proved unfounded and Beckham appears to have improved his game while in Spain.
He has developed as a midfielder playing in a more central role.
Quite simply the heartbeat of Eriksson's England, he has flourished alongside Zinedine Zidane, Ronaldo, Luis Figo and Roberto Carlos at Real.
Nicky Butt
Born: 21/01/75
Position: Midfielder
Club: Manchester United
Caps: 33
Goals: 0
Came to prominence during an impressive series of displays for England in the 2002 World Cup, and has become a reliable option for Sven-Goran Eriksson.
Returned to the England starting line-up against Turkey and enjoyed a hugely impressive display at the base of the diamond formation.
May not be a regular at Manchester United and at one stage looked to be moving elsewhere in the Premiership, but his experience and solidity make him a serious option for Eriksson.
Butt is an ideal alternative for the drive of Steven Gerrard and the attacking instincts of Paul Scholes.
Joe Cole
Born: 08/11/81
Position: Midfielder
Club: Chelsea
Caps: 15
Goals: 2
Cole's £6.6m transfer to Chelsea during the close season put him firmly in the spotlight, and Blues boss Claudio Ranieri is far from being his only admirer.
His vision and invention are not in question, but Cole needs to show he has the maturity to go with the tricks if he wants to prove he is worth a permanent place on the international stage.
Cole, despite regularly being little more than a substitute at Stamford Bridge, was called up for England's friendly against Denmark and did his cause no harm by scoring.
But he faces a fierce fight in one of the most hotly-contested areas of Eriksson's side.
Kieron Dyer
Born: 29/12/78
Position: Midfielder
Club: Newcastle
Caps: 20
Goals: 0
Has been considered one for the future by England for some time, and will now be hoping to fulfil his potential and establish himself in the team.
Filled the problem left-sided role for the first game against Liechtenstein but was relegated to substitute as England beat Turkey with Steven Gerrard on the left side of a diamond formation.
Dyer's vast reserves of energy and his eye for a goal have marked him out as a player who could potentially make a massive impact at the Euro 2004 finals.
Steven Gerrard
Born: 30/05/80
Position: Midfielder
Club: Liverpool
Caps: 22
Goals: 3
Gerrard's tenacity, drive and perceptive passing make him an essential part of England's midfield, where some say he is even more important than David Beckham.
Allied to this is a good understanding with club colleague Michael Owen - and a reputation as a lucky talisman, as England are yet to lose in a competitive match in which Gerrard has played.
Gerrard, when fit, is one of the finest midfield operators in Europe with a growing reputation.
He still has question marks over his temperament, but has vowed to clean up his act.
Owen Hargreaves
Born: 20/01/81
Position: Midfielder
Club: Bayern Munich
Caps: 17
Goals: 0
A hard-working, versatile midfielder who was part of England's World Cup squad.
Hargreaves is a key component of his club side Bayern Munich and impressed when they won the Champions League title in 2000.
England coach Sven-Goran Eriksson is a great admirer of Hargreaves, who can play in midfield and at right-back, and has great faith in his attitude and ability.
Hargreaves' experience in the Bundesliga also adds an extra European dimension to the England squad.
Frank Lampard
Born: 20/06/78
Position: Midfielder
Club: Chelsea
Caps: 17
Goals: 1
Lampard has been in superb form for both England and Chelsea this season.
The midfielder scored a brilliant goal in the friendly against Croatia and impressed in the match against Denmark.
Lampard has matured into a fine example of the modern midfield player since his move from West Ham and has established himself as a regular in the Chelsea team despite intense competition for places.
He is defensively aware but also has the ability to burst forward from midfield and scores more than his fair share of spectacular goals.
Paul Scholes
Born: 16/11/74
Position: Midfielder
Club: Manchester United
Caps: 60
Goals: 13
Once England's most prolific midfield goalscorer, the goals have dried up for Scholes.
Scholes has not scored at international level since June 2001 against Greece but remains one of the first names on Sven-Goran Eriksson's teamsheet.
He is, despite a barren spell in front of goal, England's most technically gifted midfielder who can create chances with his intelligent passing.
Scholes also has vast, and invaluable, experience at the highest level for club and country.
