The general director has reacted to criticism of the Bianconeri's recent transactions, insisting the club have made positive strides forward over the past two years
The Old Lady are the reigning Serie A champions and remain unbeaten in their last 47 league encounters. But, some fans remain unhappy with a number of deals and voiced their concerns at a shareholders' meeting on Friday - with Marotta hitting back.
"It's true, errors have been made," said the general director.
"Over the last two years we have had to oversee, not a revolution, but a significant rejuvenation. We’ve signed 22 players and you can get a few signings wrong.
"But don't forget about [the signings] we got right. Andrea Pirlo on a free, Paul Pogba and Arturo Vidal – a player we signed for €10m and one for whom we rejected an offer of €30m.
"We turned that down because Juventus are not a selling club."
Marotta also claimed that Juve made the right decision to sell Ciro Immobile to Genoa in a co-ownership deal, and gave an example of how loan moves can work well.
"In order to get the best out of youngsters, you have to give other clubs an incentive to do that,” he continued.
“Simple loan moves often don’t work in the same way. Look at Sebastian Giovinco. We sold a half share in him for €4m to Parma and we signed him back for €11m – now he is a €15m player."
