The Croatian is currently a first-team regular at the Volkswagen-Arena but has already received assurances from Mark Hughes on the style of play on offer at the Britannia Stadium.
Olic would be available on a Bosman transfer at the end of the season and is being mooted as Hughes' first choice target.
The 34-year-old admits he did make a trip to England last week, but still remains coy on his future.
"Me and my wife were in England last week," Olic told BILD.
"We liked what we saw. Still, I have not made a decision on whether I will be staying or leaving Wolfsburg."
Wolfsburg general manager Klaus Allofs insists the club have made their stance clear to Olic, but claims the club are not willing to compromise.
"We have made things clear to Ivica Olic," Allofs stated. "He knows what he is going to expect if he signs a new contract with Wolfsburg.
"I do not want player in the squad that are unsure if Wolfsburg is the best club for them."
