Southampton announced this afternoon that Virgil van Dijk has signed a new contract that will run until 2022.
The centre-back joined Ronald Koeman's side from Celtic in the summer and has become a key part of the Saints team this campaign.
The Dutchman has made 36 appearances in all competitions and has scored three goals for the Saints. His form in the opening stages to his Premier League career was rewarded with a national team debut in October.
Executive Director of Football Les Reed said: "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."
"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."
