The Turin side have been heavily linked with a big-money move for the Uruguay international, who has scored 22 goals in 29 Premier League appearances this term.
Last week, Suárez revealed he would be open to talking to clubs who could offer Champions League football in the summer, with Juve reported to be leading the race.
“Who would I like as a birthday gift between Sanchez and Suárez? I am happy with our players and I cherish them. At this time of the season, we don’t think about the [transfer] market,” he told Italia 2.
“Ibrahimovic? He is a champion, but Juventus has economic parameters, which must be respected, and his salary is higher than these.”
Marotta also moved to quash talk of Juve manager Conte leaving the Turin outfit at the end of the season.
“There is not clause in his contract, but I think he will remain for many years and may get a lot of satisfaction from Juventus,” he added.
Conte’s side are nine points clear of second-place Napoli in the Serie A title race this season.
