Reigning PFA Players' Player of the Year winner Virgil Van Dijk has named Sergio Aguero as the toughest opponent and Roberto Firmino as the best player he has played with.
Van Dijk had an outstanding campaign with Liverpool last season as he helped the side to their sixth Champions League crown and finished a point behind Manchester City in the English Premier League. His performances earned him the Players' Player of the Year award and is a strong contender for the Ballon d'Or.
In an interview with talkSPORT, Van Dijk revealed his toughest opponent, "I’m going to be a little bit biased and say one of my team-mates; I would say Roberto Firmino." When asked the most difficult striker to mark in the Premier League the Dutchman said, "Sergio Aguero".
