With the Rossoneri currently on a five-game unbeaten run in the league, De Jong believes that Inzaghi should take plenty of credit for the side's recent form.
"The coach has done a good job with us, he's always very positive," the Dutchman told the club's official website. "We believe and we never give up, just like our fans. We do this for our fans and for the club, which is very important."
De Jong found the net against Fiorentina on Sunday to make it two goals in seven games for him this season.
