Ledley King's playing future is on the line at Tottenham.

The London Evening Standard says have a clear idea of the players they want to compete for central defensive positions next season: Younes Kaboul, Michael Dawson, Steven Caulker and Jan Vertonghen, from Ajax.

King has been a member of the first team since May 1999 but he has not been offered a new contract and must convince the medical team his knee can stand up to the demands of another Premier League season.
