Olic is desperate for regular first-team football at Bayern Munich after recovering from a long injury.
Olic scored the opening goal in Croatia’s 3-0 win over Turkey in the first leg of their Euro 2012 play-off tie on Friday.
“This game confirms my opinion,” the 32-year-old told the Suddeutsche Zeitung newspaper.
“If my situation does not change, then I will try to leave this winter. I can still play two more years at the highest level.”
