He said: "Nothing is sure. There is interest but it is not the time for all parties to say something about it. A lot of things are being said and written and it's a bit chaotic. From our side we are just keeping quiet and we will see what happens."
Van Ginkel is highly-rated in Holland and has already earned a cap for the national team. Vitesse Arnhem team-mate Theo Janssen revealed earlier this week that he has told Van Ginkel to make the move to west London should a fee be agreed.
He said: "If he thinks he's ready for the next step, then he must do it. I think he is ready but the step to Chelsea is very big.
"It's the plan that he'll join the Chelsea squad, learn a lot and play on a regular basis. It all looks very positive but he must make his own decision. I told him that opportunities like this don't come that often and, if you get a chance like this, then you must do it."
