Zarate is back in the first team reckoning after Stramaccioni replaced Claudio Ranieri.
"Stramaccioni is giving me the chance to play and tells me to do what comes into my mind, because he believes in my qualities," Zarate told Inter Channel.
"He asks the team to attack and all the forward-pushing players have to make the difference. For someone like me it is crucial to dribble and seek the one-on-one.
"Now we are closer to third place and must do our best in the next two games, as we want as many points as possible.
"They will be difficult matches, but they will allow us to understand if we can really achieve Champions League qualification or not.
"I am convinced it is possible and our heads are entirely focused on this objective."
