The former Liverpool, Aston Villa and England striker has netted four goals in four outings for the Jets and former Crystal Palace and Socceroos centre-back knows it is very important to try and keep him under wraps to give themselves every chance of recording a third straight win.
"You prepare well for every opponent and opposition," Popovic said.
"We certainly make the players aware of Emile's strengths and we'll do our best to make it a quiet night for him tomorrow.
"From our point of view we just need to worry about our performance and make sure that our structure is right.
"If we can do that, we give ourselves a good chance of winning the game."
The Wanderers currently sit sixth on the 10-team A-League table with seven points from five matches whilst Heskey's Jets are fourth with three wins and two losses.
