The Bianconeri general manager has voiced his dismay with the Roma trainer's latest outburst, and urged the coaching union to take measures against the Czech
The 65-year-old claimed over the weekend that the Juventus boss' ban should not allow him to train his team during the week, and the general manager feels the Czech's remarks were out of order.
"As a football man and the general manager of Juventus, I feel Zeman's comments are inappropriate," Marotta told Sky Sport Italia.
"He was referring to Conte even though he didn't mention him specifically. It was either a joke, and therefore a worthless comment, or an intentional jibe.
"He admitted that he hadn't read the documentation himself and that he couldn't explain this first-instance ruling given to a fellow coach from the same association, who has been sentenced for failure to report rather than for any violation.
"I find these latest remarks by Zeman out of place. He had his say on Juventus' titles just two weeks ago and now he is speaking out against a fellow manager, which I think is even more serious.
"I hope the president of the coaches' association takes a stance on this matter because situations such as these only create more tension in what is already a delicate time for Italian football."
Juventus beat Napoli 4-2 in the Supercoppa Italiana over the weekend in their first match without Conte.
