Tottenham defender Steven Caulker has committed his future to the club by signing a new long-term contract until 2016.
The centre-back has been with Spurs since the start of his professional career but has spent the past few seasons gaining experience with a succession of loan deals.
Having spent time with Yeovil and Bristol City, Caulker then linked up with Swansea on a year-long agreement last summer.
He produced a series of impressive performances to help the Swans finish in mid-table in the Premier League, and has earned a call-up for the Team GB Olympic squad.
There had been talk of Caulker staying at the Liberty Stadium for the 2012/13 campaign, but Tottenham have now moved to ensure he will remain on their books for at least another four years.
The 20-year-old will have the chance to work with incoming Spurs manager Andre Villas-Boas, who declared when he was appointed that he shared the club's vision for developing players and nurturing young talent.
Caulker will also be reunited with Gylfi Sigurdsson, who spent the second half of last term on loan at Swansea before on Wednesday becoming Villas-Boas' first signing at Tottenham.
Caulker's focus for the next few weeks will be on the Olympics, though, and he admits it was a proud moment to get the final nod from Stuart Pearce.
He told Tottenham's official website: "When I was told I was in the initial squad of 35 I just hoped I would get the call.
"The call came and now it's a case of getting ready for the Olympics.
"I'm delighted to be part of it and the fact it's here in Britain means it will be a huge event and something I'll no doubt look back on for many, many years."
