Villa have until the end of the month to register whether they want to take up a one-year option.
But boss Martin O'Neill wants to offer what is likely to be a three-year deal.
O'Neill said: "I have spoken to his agent last week and I was hoping to get out and meet him this week.
"I can go to Holland or he can come here. He was in Valencia when I was speaking to him because he also deals with Ronald Koeman. There are no problems and we're definitely going to meet up."
