#4 Virgil van Dijk
Virgil Van Dijk has cemented his reputation as one of the best centre-backs in the world with his world-class displays for Liverpool this season.
The Dutchman's commanding presence in the backline helped Liverpool keep three successive clean sheets in the league in April, against Chelsea, Huddersfield and Cardiff.
Another clean sheet against Porto in the first leg of their Champions League quarterfinal tie meant Liverpool had one foot in the semifinal, and Van Dijk followed it up by netting a goal of his own in the return leg to secure their progression.
While he met his match against Barcelona and Lionel Messi in the semifinal, it was arguably one of his only poor displays all season.
Van Dijk was rewarded for his consistently brilliant performances with the PFA Player of the Year award and if he can help Liverpool to a historic Premier League title, he will surely be able to crack the top two in this list.
