O'Donovan, with seven goals in five games this season, looms as the decisive figure when the Jets make the trip down south.
But the Irishman knows German manager Kurz will have plans in place to halt his scoring spree.
"The style of football (coach) Ernie (Merrick) wants us to play, the personnel we have, it all gears itself towards me getting some chances and goals," O'Donovan told reporters on Friday in Newcastle.
"But I'm sure Adelaide have done their homework and will have their defensive structure tweaked a little bit for tomorrow's game.
"For me, Adelaide is a very difficult one because they have probably been the most-effective team since they have had the new manager come in this year.
"They're in the FFA Cup final ... they're a standout so far."
Kurz's Reds sit in fifth spot on the ladder, six points behind the third-placed Jets. And the German boss confirmed O'Donovan was looming large in his pre-game plotting.
"O'Donovan is the best scorer in the A-League and I know that we must be awake for 90 minutes and defend extraordinary good (sic)," Kurz said.
But Kurz was also demanding an improvement in Adelaide's attacking firepower - his side have the most shots on goal this season, but fewest on target.
"One of the main focuses in training this week was to create chances and to finish them," Kurz said.
"We had a lot of good moments in all games we have played in the past but we did the wrong decision at the last pass. We must get more shots on target."
