Green has superb reflexes and command of his area, but suffered a crisis of confidence when his horrendous error let USA claim a 1-1 draw in the World Cup.
He first made his mark when he helped Norwich City win promotion to the Premier League as 2003-04 First Division title winners. He conceded just 39 goals during the season and was rewarded with a call-up to the England squad by Sven-Goran Eriksson in March 2004 for a friendly against Sweden. The Chertsey-born keeper had to wait for an end of season tour to the USA in the summer of 2005 to make his England debut and he was all set to go to the 2006 World Cup in Germany, but ruptured his groin in a B international against Belarus, just a few weeks before the tournament.
After making over 220 league appearances for Norwich, Green joined West Ham United in August 2006 for a bargain £2 million transfer fee and was one of the stars of the Hammers' successful bid to stay in the top flight in the 2006-07 season. His performance against Arsenal at the Emirates, in which the Hammers became the first visiting club to win there, goes down as one of the best in Premier League history. He remains one of West Ham's main assets.
Strengths: A great shot stopper, whose agility allows him to make some eye-catching saves.
Weaknesses: Can sometimes flap at high crosses delivered into the penalty area and his kicking has been suspect at times.
Career high: Keeping goal in the 5-1 win over Croatia at Wembley in September 2009 when England booked a place at the 2010 World Cup in South Africa.
Career low: Letting the ball slip through his grasp against the USA in the 2010 World Cup. He was dropped from the side after that.
Style: Confident, calm, a goalkeeper who does the simple things well.
Quotes: "Over the last year his form has been excellent. I have obviously been playing with him at that time at West Ham and I can't remember any kind of mistakes. It's down to him and his performances now, which is all you can ask for." West Ham team-mate Matthew Upson, September 2009.
Trivia: In 2008, Green climbed Mount Kilimanjaro to raise funds for the African Medical and Research Foundation.
