Tottenham confirmed midfielder Erik Lamela had joined forward Son Heung-min in signing a new contract extension on a busy afternoon of announcements for the Premier League club.
Manager Mauricio Pochettino has so far not yet strengthened a squad which finished third last season, but has been able to tie down two of his key players.
South Korea international Son, who caught the eye at the World Cup, scoring against holders Germany in the final group match, has signed a deal to stay with Spurs until 2023.
Lamela, meanwhile, sees his new contract run through until at least 2022.
Son has forged an excellent working relationship with England captain Harry Kane, scoring 26 league goals across the last two campaigns.
The 26-year-old, who joined Spurs from Bayer Leverkusen in 2015, is determined to continue his progress under Pochettino – and “make some history” with the north London club, who are set to move into a new stadium next season.
“I’ve learned so many things in the last three years and we’re all looking forward,” he said on the club’s official website.
“We deserve to win something and deserve to make some history. It’s time to do it and to believe in ourselves.
“I’m always positive with the lads and looking forward to playing again in the Premier League and the Champions League.”
Lamela can also expect to be an integral part of the Spurs team next season, having returned to action in November 2017 after more than a year out because of a hip problem.
The midfielder went on to make 33 appearances over the remainder of the 2017-18 campaign, and scored twice as Spurs beat Leicester 5-4 at Wembley on the final day of the season in May.
In a brief video on Tottenham’s official Twitter feed, Lamela said: “I am delighted to sign a new contract. I hope to see you next season in the stadium. I can’t wait.”
Tottenham, who have been linked with a move for Aston Villa midfielder Jack Grealish, are set to head off on a pre-season tour of the United States as focus turns towards the start of the new domestic campaign.
Pochettino’s squad will compete in the International Champions Cup, with matches against AS Roma (San Diego), Barcelona (Los Angeles) and AC Milan (Minneapolis).
