Klopp was asked about the Dutchman after their friendly win at Tranmere Rovers last night.
He is quoted by the Liverpool Echo: "Am I allowed to talk about this? I am not! Pretty much everything I could say would be a mistake.
"You or your colleagues wrote everything about this a few weeks ago. I was in Iceland by the way when somebody told me this was in the newspaper.
"Nothing happened since then, all good so far, so I can't say anything about this."
