Vertonghen's joy at new Spurs deal
Defender Jan Vertonghen has signed a new contract at Tottenham that will run until 2019, the club have announced.
Vertonghen has been in negotiations since the end of last season and his new deal extends his commitment to Spurs by a year.
The Belgium international moved to White Hart Lane in July 2012 from Ajax and has become a key figure under manager Mauricio Pochettino.
"I was very happy once I put my autograph on the paper," Vertonghen said.
"I was extremely happy, big relief. I'm very happy to be here, the future looks great so I am very happy to be a part of it.
"This is an unbelievable group of talented guys and I feel privileged to be a part of that. There's a great atmosphere in the team and a great buzz around Tottenham."
Vertonghen's partnership with Toby Alderweireld last season was crucial to Tottenham launching a surprise title challenge and qualifying for the Champions League.
Their defensive record of 35 goals conceded was the joint-lowest in the Premier League. The announcement comes 24 hours after Harry Kane extended his contract until 2022 and continues the club's drive to secure the futures of first-team players.
Eric Dier, Dele Alli, Christian Eriksen, Kyle Walker and Danny Rose have all signed new deals since the start of the season, while Spurs also hope to persuade their captain and goalkeeper Hugo Lloris to follow suit.
"It feels great to be a little part of the big part Tottenham is. I can't imagine playing somewhere else at the moment," Vertonghen said. "This is probably the strongest squad I've ever played in and I think everyone agrees with me."
Vertonghen is into his fifth season at Tottenham since moving from Ajax and the 29-year-old has made 179 appearances for the club.
Tottenham hoped Moussa Sissoko might provide the incision Sigurdsson has been giving today's opponents Swansea but the Frenchman is yet to make an impact since his big-money move in the summer.
Pochettino criticised Sissoko's contribution following last weekend's defeat to Chelsea but the Argentinian admits his new signing has not been helped by some events out of his control. "It has been difficult," Pochettino said.
"He signed on the last day, August 31, he goes to France for international duty, without pre-season, he came back, he got concussion, he was suspended for three games, so it was very difficult for him."
