Celtic have snapped up FC Groningen defender Virgil van Dijk for a fee reportedly worth up to £2.5 million.
Van Dijk, 21, who arrived in Glasgow for talks with the Scottish champions on Thursday, has signed a four-year deal at Celtic Park.
The Hoops announced the signing of the Netherlands Under-21 international, who started his career at Willem II, via a statement on their official website on Friday.
The statement read: "Celtic are delighted to announce that defender Virgil van Dijk has joined the club from FC Groningen.
“The Dutch Under-21 international has signed a four-year deal with the Scottish Champions, and he becomes the latest player to join Neil Lennon's squad during the close season following the arrival of striker Amido Balde from Portuguese side, Vitoria Guimaraes.”
Van Dijk, who was officially unveiled at Celtic Park on Friday afternoon, said he was delighted to have completed a move to Scotland.
“It feels very good and I’m very excited to be here,” he told the club’s official website. “I’m really looking forward to playing here for Celtic.
“Celtic is the biggest club in Scotland and they also play in the Champions League. They’re a fantastic club and when Celtic came in for me I was so excited. Everything here is good so I can’t wait to get started.
"I hope to play many games for my country in the future but first of all I want to make things happen here.”
