Marotta also praised president Andrea Agnelli over his appointment of coach Antonio Conte.
"We are proud to have created with Juventus the model for a football club. It all started with the return of an Agnelli to the Presidency, who gave everyone a sense of belonging," he told the Corriere dello Sport.
"We also must not underestimate the structure, where everyone has their own specific tasks. The Coach also knew the environment and what it meant to be a Juventino. Choosing Antonio Conte was down to Andrea Agnelli."
