Heynckes repeatedly spoke about the desire of his side following the heartbreak of last season's penalty shoot-out defeat to Chelsea.
He believes it has fired their resurgence this term and warned Arsene Wenger that, for all his goodwill, his side believe they can head back to the Allianz Arena with an advantage in the tie.
"We've shown this already in the league, cup and Champions League that we have this desire," said Heynckes, who is set to be boosted by record-signing Javi Martinez's return from injury on Tuesday.
"You have to have that. We will need to defend like we have tomorrow.
"Arsenal is a very good team especially going into attack. We are going to have to stand strong and then work our way forward.
"I don't have a result that I wish for but I do believe that if we play to our capability then we can win here."
