The Bianconeri official revealed that signing the Dutchman would be a hard task for any side from the peninsula, whilst clarifying what happened with Dimitar Berbatov
The Bianconeri official also insisted that there was no wrongdoing against Fiorentina in regards to the potential transfer of Dimitar Berbatov, who eventually snubbed the two teams in favour of Fulham.
Nevertheless, Marotta revealed that whilst signing the former Arsenal captain was an objective, the transfer fee was not a feasible option for any Italian side in the current climate.
"Last year we were able to hit a record [that is] hard to beat [such] as ending the season unbeaten. We had some goals and not all of them have been achieved," the 57-year-old told Sky Sport Italia.
"I take the example of Van Persie. [He] is impossible for an Italian club right now. Spending €30 million on a player, not to mention the wages, is not feasible [for] Juve or for any other club in Serie A.
"[The] Berbatov case? I hope to meet with President [Andrea] Della Valle soon to clarify the situation of Berbatov, but I want to clarify that there was no misconduct against Fiorentina.
"We made an enquiry after the player said he did not want to go to the Viola, but it was off very shortly because he said he preferred Fulham."
Marotta also turned his attention to the Champions League group stage, where the Serie A holders were drawn against Chelsea, Shakhtar Donetsk and Nordsjaelland.
He continued: "We are pleased to return to an important competition like the Champions League. Although we can't say [we are] on par with the four or five most important clubs in Europe, we will focus especially on the way we play and on strengthening.
"[Progressing from] the group is within our reach, even though there are dangers hidden around the corner. Just look at Basel and Apoel last year."
