Virgil van Dijk has established himself as one of the world's best players at Liverpool.

Ever since the moment he scored in the Merseyside derby on his debut, it seemed as though the Reds had bought the missing piece in the puzzle and £75 million has never looked so cheap.

Fast forward 18 months and Van Dijk is now a Champions League and UEFA Super Cup winner as well as the holder of the PFA Player of the Year award.

You face a pretty hard argument claiming that anybody other than Van Dijk is the world's best defender and he's now one of the leading contenders for the Ballon d'Or.

In summary, Van Dijk is currently loving life in the world of football and talkSPORT decided to quiz him on some major questions in the midst of his recent success.

Van Dijk calls Ronaldinho the GOAT

Arguably the stand-out question was who Van Dijk considers the greatest player in history, which often produces an answer of either Cristiano Ronaldo or Lionel Messi for his generation.

However, Van Dijk actually believes that Ronaldinho - one of his self-proclaimed heroes growing up - is the GOAT as opposed to any of his contemporaries.

While there aren't necessarily many football fans who would second that opinion, Ronaldinho remains one of the most loved players in history for his entertaining style of play.

Besides, his trophy cabinet contains winners' medals for the Champions League, World Cup, Copa America, Olympics, La Liga and Serie A as well as the 2005 Ballon d'Or crown.

But that wasn't the only killer question that Van Dijk was tasked with, so check out the full transcript to find out his toughest opponent, favourite stadium and much more.
