Tottenham defender Steven Caulker has signed a new four-year contract, the Premier League club says.

The 20-year-old has also established himself as a regular in the England Under-21 set-up and was recently called up to the Team GB football squad for the Olympics.

Caulker signed his first professional deal with Tottenham in 2008 and he has since enjoyed successful loan spells at Swansea, Yeovil and Bristol City.

The Londoner has only made one appearance for Tottenham – two years ago in the League Cup defeat to Arsenal – but he is expected to challenge for a first-team place next season under new boss Andre Villas-Boas.
