Soccer: Tottenham defender Ledley King has announced his retirement but will stay on at Spurs as a club ambassador. King, who has captained the side since 2005, has suffered from chronic knee problems in recent years, limiting his game and training time.

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 came through the youth ranks at Spurs before stepping up to the first team in 1998. The London-born centre back went on to make more than 250 appearances for the White Hart Lane club, the high point coming when he lifted the League Cup in 2008 with victory over Chelsea.

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.”

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.”
