Eye injury forces Sutton to quit 
Striker Chris Sutton has decided to retire from football because of a problem with blurred vision.
The 34-year-old was at Aston Villa last season but missed the second half of the campaign after experiencing eye trouble in a match in December.
"I spoke to Chris on Wednesday and, given the eye problem, he has decided to retire," said agent Tony McGill.
Sutton, who started his career with Norwich in 1991, made one appearance for England - against Cameroon in 1997.
The Nottingham-born player started out as a defender with the Canaries, making his debut against QPR in 1990.
But he was bought as a forward by Blackburn for £5m in 1994 - a British record transfer fee - and was part of the Rovers team that won the Premiership in 1995.
Sutton also played for Chelsea, Celtic and Birmingham before signing for Villa in October 2006.
"If Chris had declared that his eye was OK he would probably have got another year at Villa," added McGill.
"But he decided that he could not do himself justice with the eye injury and, more importantly, he has taken into account the effects it might have on his future life.
"It is disappointing but it is not as though he is starting his career."
Chelsea paid £10m for Sutton in July 1999 but he scored only one Premier League goal for the London club before moving north to Celtic 12 months later.
Sutton won three Scottish Premier League titles, two Scottish Cups and one Scottish League Cup at Celtic and played in the 2003 Uefa Cup final.
He struck up a formidable strike partnership with Henrik Larsson and received the Scottish Professional Footballers' Association players' player of the year award in 2004.
Sutton joined Birmingham in January 2006 but the move did not work out as Blues were relegated, so he sealed a move to Villa.

He has had an amazing career, it is a shame that it has to end like this but lets face it, it was nearing a close anyway at 34 years old. He has done well to be one of the players over 30 to remain in the top flight.
