The Dutchman gave Van Dijk his first team debut and told talkSPORT: "I'm bias anyway, so I would choose Virgil. He has more, he has a little bit more.
“Vidic, of course, without any doubt was a very good player, he played in a top team.
“In my view, Virgil has everything. He has the flair, he has the technique, he has the passing, he has the defensive leadership, he has the personality that catches people's eye.
“I just admire the strengths of certain players.
“There have been very good defenders in the Premier League and when you [Van Dijk] are talked about in that group of players then it's a good honour."
