Southampton defender Virgil van Dijk has signed a new six-year contract, which will run until 2022.
Van Dijk, 24, has impressed since moving from Scottish champions Celtic in the summer of 2015 and he was rewarded by a callup to his national team, and he made his debut for Netherlands in a 2-1 win against Kazakhstan in October.
"I'm so pleased, I'm so happy. Me and my family have enjoyed it a lot this year. It's been amazing. It's only positive," Van Dijk told the club website.
"The club is growing and I definitely want to grow with them, that's how I feel. Hopefully we can make it happen. That's the plan, to get a lot of achievements going."
Executive director of football Les Reed added: "In his first year with the club, Virgil has quickly established himself as one of the top centre-backs in the Premier League, becoming an integral part of what has been another strong season for the team.
"At 24, and with significant European experience already under his belt, we believe he can be a key pillar in our squad for years to come, and we are delighted to have agreed this new deal with him.
"Although Virgil only joined us in September we felt it was important to strengthen our commitment and we believe this also provides further indication of how serious our ambitions are for the coming years."
Van Dijk, who cost the Saints £11.5 million, is expected to start Sunday's clash with Tottenham at White Hart Lane.
