Virgil van Dijk in action for Southampton
Former Netherlands star Ronald de Boer admits he has been surprised by the ‘unbelievable progress’ Virgil van Dijk has made.
Van Dijk has been outstanding for Southampton since arriving from Celtic in 2015 and is one of the most sought-after centre-backs in the Premier League, with Chelsea, Liverpool and Manchester City all rumoured to be interested in securing his signature.
De Boer had his doubts about his fellow Dutchman when he was a youngster starting out at Groningen, but says he now rates the 25-year-old as one of the best defenders around.
