Christian Eriksen, Danny Rose and Eric Dier among those to sign new deals recently.
Jan Vertonghen has become the latest player to commit his future to Tottenham Hotspur, signing a new contract tying him to the club until 2019.
Vertonghen, 28, follows Harry Kane in extending his stay at White Hart Lane, after the England international signed a new deal with the club on Thursday (1 December) until 2022.
Vertonghen told the club's official website: "I was very happy, once I put my autograph on the paper I was extremely happy, a big relief. I am 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 talent and a group of guys, I feel privileged to be part of that. We have created a great atmosphere in the tram and there is a great buzz around Tottenham."
After manager Mauricio Pochettino signed a long-term contract at the end of the 2015-16 season, Tottenham have set about tying all of their first-team options down to new deals.
Danny Rose, Kyle Walker Christian Eriksen, Harry Winks, Tom Carroll, Eric Dier and Dele Alli have all committed their futures to the club this season. Centre-back Kevin Wimmer also penned a new contract in July, while Erik Lamela is reportedly in talks to do the same in the near future.
Hugo Lloris could become the next Tottenham star to renew. Pochettino explained at a press conference on Thursday: " Maybe you need to ask Hugo and the chairman. Maybe in the next few days you'll see more news.
"Hugo is a very ambitious player, but he's very happy here. I can only tell you that he's very happy here and he wants success here at Tottenham. That's his ambition."
Vertonghen is currently enjoying his fifth season at Tottenham, having joined the club from Ajax in 2012.
Last season he formed one of the Premier League's most formidable centre-half partnerships alongside countryman Toby Alderweireld as Spurs challenged for the Premier League crown, with the club finishing the campaign with the joint-best defensive record.
