Hosiner, who scored an impressive 32 goals in 34 games for the club last season, has two years remaining on his current deal.
The Austrian club are understood to be holding out for a fee in the region of £4.5m for the 24-year-old.
But Hosiner inists his priority is helping his side try and qualify for the UEFA Champions League as they prepare to face Icelandic opponents Hafnarfjordu in the third qualifying round of the competition.
"At this point in time I would like to have my peace," he told Austrian-based newspaper Osterreich.
"We have an important play-off match coming up and then after that I will listen to all enquiries with my agent.
"After that, we will see if it's worth me leaving such a great club like Austria Vienna."
