Marotta is confident of Conte's commitment.
"Any interest means that Juventus have great players and a great Coach, which is something to be proud of," director general Marotta told Sky Sport Italia.
"Having said that, I think Conte has a strong Bianconeri DNA, so feels happy on a professional level.
"A contract is a mere piece of paper, but there is a strong rapport with President Andrea Agnelli, the directors and players.
"Conte is at the centre of our project, so I think he will be with us for many years."
