Son Heung-min has signed a new long-term contract at Tottenham, while Erik Lamela has signed a four-year deal.
South Korea international Son, 26, has signed a five-year deal, committing himself to the club until 2023.
Son scored 18 goals in 53 appearances for Mauricio Pochettino’s side last season.
He joined Spurs from Bayer Leverkusen in 2015 and has since scored 47 goals across 140 appearances.
Son represented his country at the World Cup in Russia and Tottenham say he is now ready to link up with his club-mates ahead of the pre-season tour of the United States.
Son has forged an excellent working relationship with Spurs striker Harry Kane, scoring 26 league goals across the last two campaigns while the England international has notched 59 in the same period.
In a video tweet posted by Spurs, Son said: “I’m very happy to sign a new contract. I hope to see you this season at the new stadium.”
He will also represent his county in the Asian Games, the club confirmed.
A Spurs statement said: “Son will now join up with the squad ahead of our tour of the United States where we will compete in the International Champions Cup against AS Roma (San Diego), Barcelona (Los Angeles) and AC Milan (Minneapolis) and will also be available for our opening game of the Premier League season away at Newcastle United before travelling to Indonesia to represent South Korea at the Asian Games.”
Lamela, 26, joined Spurs from Roma in 2013 and has scored 23 goals in 154 appearances.
He was sidelined for more than a year after suffering a hip problem on 2016, returning to action on November 28 last year as a late substitute in the 2-1 defeat at Leicester.
The midfielder went on to make 33 appearances over the remainder of the 2017-18 campaign, and scored twice as Spurs beat the Foxes 5-4 at Wembley on the final day of the season in May.
