Van Dijk missed only 35 minutes of the Reds’ 37 matches before the campaign finale on Sunday, helping to register 20 clean sheets and scoring four goals.
The No.4’s imperious form – which also earned him the PFA Players’ Player of the Year honour last month – has been a significant factor in Liverpool’s pursuit of the Premier League title.
Van Dijk saw off competition from teammates Sadio Mane and Mohamed Salah, Manchester City trio Sergio Aguero, Bernardo Silva and Raheem Sterling, and Chelsea’s Eden Hazard, to claim the accolade.
The winner was decided by a combination of votes from fans, the captains of the 20 Premier League clubs, and a panel of football experts.
