The Phobians, who travel to Techiman on Sunday to face debutants Eleven Wonders on matchday one, have gone nine seasons without a major title and have appointed more than ten coaches in the process.
"Hearts of Oak is a big club and the expectations from supporters are always very high but like I've always said, if we want to achieve our goals and be able to win the league title, we have to lower our expectations," Opare told Happy FM.
"I want us to take each match after the other so that we can amass enough points and make an impact. I want to reiterate that we'll compete for the top-most award this season and that's the premier league title," he added.
Hearts are currently without a head coach after the sacking of Frank Nuttall and Henry Wellington has been tasked to lead the club on the interim.
