Lamela joins Son in signing new long-term deal at Spurs
Tottenham have confirmed that midfielder Erik Lamela has joined forward Son Heung-min in signing a new contract extension.
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.
Winger Lamela sees his new contract run until at least 2022.
Son (26), who joined Spurs from Bayer Leverkusen in 2015, is determined to continue his progress under Pochettino.
"I've learned so many things in the last three years and we're all looking forward," he said.
"We deserve to win something and deserve to make some history. It's time to do it and to believe in ourselves."
Lamela said on Spurs' Twitter: "I'm delighted to sign a new contract. I hope to see you next season in the stadium. I can't wait."
Tottenham have been linked with Aston Villa's Jack Grealish.
