Olic made England trip

The Croatian has scored 11 league goals in 27 appearances for the Bundesliga outfit this season, but Stoke City have been linked with a close-season move for the 34-year-old, when he would be available on a free.

And Olic revealed that he made a trip to the UK last week, but remained tight-lipped on his future.

"Me and my wife were in England last week," Olic is quoted as saying by Bild. "We liked what we saw. Still, I have not made a decision on whether I will be staying or leaving Wolfsburg."

"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."
