Tottenham captain Ledley King has announced his playing retirement.

The 31-year-old admitted the decision to quit was tough, and, after spending his entire career at the club, he could not consider playing elsewhere.

King told the club's official website: "I would like to say thank you to everyone at the club and to the fans. I have missed a lot of football over the years, but the Spurs fans have always been patient and incredibly supportive with me during difficult periods.

"Sadly my injuries and inability to train have now finally brought an end to my career.

"I have been here since I was a boy, I have always considered it my club and have always found it hard to imagine wearing the shirt of another team.

"I know that being a one-club man is a rarity these days, but I have always enjoyed being part of the set-up here and the challenge of putting this club up with the elite where it should be."

Tottenham chairman Daniel Levy hailed King's impact at the club and said he would continue to represent them in a new capacity.

"Ledley has made a magnificent contribution to this club - as a wonderful player, captain and ambassador," Levy said.

"It has been well documented how he has battled against injury over the years and it is testament to the character of the man how he managed to sustain such high standards of performance on the pitch, while providing such fine leadership.

"It is in an ambassadorial capacity that Ledley will continue, playing a crucial role in supporting the club's work in the community and the ongoing regeneration of the Tottenham area, whilst also being a hugely positive role model for our younger players."

Alongside his Spurs career King also won 21 international caps for England, making his debut against Italy in 2002 and appearing at Euro 2004 and the 2010 World Cup.

Speaking about his new role, King said: "I have been in Tottenham for around 17 years, having started at Spurs when I was 14.

"It is a second home for me and I pleased that I can continue to work within the club and for the local community, especially after the devastation caused by the riots last year.

"I am already heavily involved with the work of Spurs Foundation and the new stadium scheme will be a major factor in the regeneration of the area, so I am delighted that I shall be part of that."
