Italian teams have struggled to compete in Europe this season, with Milan the only one of Serie A's UEFA Champions League representatives to progress beyond the group stage.
Platini, who won two Serie A titles and a European Cup with Juventus during his playing days, is of the opinion that the Italian game is not as appealing to top players.
"Italian football is no less spectacular than Spanish or English," Platini said in an interview with Gazetta dello Sport.
"The image is bad, those stadiums are empty and it is sad, and not inviting to champions."
Juventus have once again dominated Serie A, winning a third consecutive Scudetto with two games still to play.
"They are physical, aggressive, offensive," Platini added. "Three Scudetti is an obligation for Juve. In Europe, they need quality and good fortune.
"I believe that (president) Andrea (Agnelli) is more attached to the Scudetto because, having to rebuild, he needed a solid foundation. But (Antonio) Conte's Juve has more grit than mine - they now want Europe."
