Marotta revealed talks to bring him to Juve were under way.
"We have an opportunity to aim for important objectives when there is the opportunity to do so," the general manager told RMC Sport.
“Emre Can's contract is expiring in June 2018.
“It's been assumed that a club like ours have their eyes and attention on him. We've opened talks with his camp, but it doesn't mean that it's done.
“It won't be easy because Liverpool will try to renew his contract, without forgetting the alternative possibility that other clubs will try to sign him.
“We'll make every possible effort to bring him in."
