King has knee surgery

Tottenham Hotspur club captain Ledley King has undergone minor surgery on his left knee.

King has been troubled by chronic knee problems throughout his career and he had an arthroscopy on Monday night.Spurs said in a statement: "Ledley King underwent a successful arthroscopy on his left knee last night."The defender is expected to rest for up to 10 days before progressing to full activity within a further 10 days."The surgery rules the defender out of the club's pre-season tour to South Africa, which begins on Wednesday.King spent a large part of last season on the sidelines thanks to a groin injury, which restricted him to just six Barclays Premier League appearances.The London club are hopeful that the 30-year-old will be fit in time for the new season, which begins on 13th August at home to Everton.King will be hoping to play a much bigger role this season although William Gallas and Michael Dawson formed a strong partnership in his absence last year.King will be hoping to persuade manager Harry Redknapp to extend his current deal, which is due to expire next summer, having seen injury-plagued defender Jonathan Woodgate released last week.Meanwhile, Tottenham have completed the signing of former Barcelona youngster Cristian Ceballos.Ceballos shot to fame four years ago when he was filmed juggling a ball with then Barca star Ronaldinho, but he did not progress as well as the Catalonian club had liked and they released him from his contract last season.The 18-year-old trained with Chelsea in March and visited Spurs' training ground towards the end of last season for a trial and his performances at Chigwell were good enough to lead the Spurs hierarchy to offer the teenager a contract.Ceballos, who can play as an attacking midfielder or forward, will now go in to the club's development squad.Spurs' technical co-ordinator Tim Sherwood said: "Cristian trained hard and showed some real quality when he originally spent time here towards the end of last season and was even involved in some of the first-team training."There was other interest in him too. He needs to be patient and if he can fulfil his potential we believe he can play at the top level."
