Conte held transfer talks with president Andrea Agnelli yesterday.
Marotta said: "There is perfect harmony between myself and Antonio.
"There really is no problem and I've already met with him.
"Some would have you understand that there are opposing views, but that is not true. Conte will train Juventus next season.
"There are all the conditions for him to stay, the President has said that too. It's useless to try and manipulate individual comments."
