It had been claimed that the Bianconeri were hoping to take the Monaco forward on loan but the Italian champions will not make any more high-profile signings this summer
The Bianconeri have been heavily linked with a loan move for the Monaco forward, who is reportedly unsettled at the Stade Louis II, with Leonardo Jardim's men having lost their first two games of the new Ligue 1 season.
However, Marotta has explained that while Juventus could sign another attacker before the close of the summer transfer window, it will not bring in a big-name player.

"We're lacking a forward, a second striker in a compartment that already gives us many certainties, but it will not be a [player with] a major profile," the Juve director told Sky Sport Italia.
"We will not make big investments. But [one player] could arrive in the final hours of the window."
It has also been reported that Juventus is considering a move for Benfica captain Luisao but Marotta insists that his team is not interested in the center back either, as he feels that the Italian champions are well stocked in defense.
"We have never contacted the player," he declared. "But this is the world of football.
"[Andrea] Barzagli is recovering quicker than expected [from injury] and [Luca] Marrone has shown himself to be comfortable in defense, so we could stay like this."
Juventus kicks off the defense of its Serie A title with a trip to Verona to take on Chievo on Aug. 30.
