The Bianconeri were stripped of their 2005 and 2006 titles because of their involvement in the Calciopoli scandal, but Marotta stressed that Juve see this year's title as their 30th success.
"It’s our 30th title as far as we’re concerned, and it's the reward of all the work done by everyone at the club, starting from [club president] Andrea Agnelli," Marotta was quoted as saying on the club's official website.
"It’s everyone’s title, but above all Antonio Conte’s. He’s the true added value and has improved the work started last year. The team have fully responded to his management."
Juventus secured the Serie A title on Sunday by beating Cagliari 2-0, while title rivals AC Milan lost 4-2 against Inter.
