The Premier League title-holders are looking to strengthen their squad as they prepare for Champions League football next term and they had earmarked Alex Sandro as a valuable potential addition.
Sandro, a Brazil worldwide who moved to the Serie A giants two years ago, still has three years to run on his current deal.
"Our desire is to not sell any of our most important players", Marotta said, as quoted on Sky Sports.
Juventus are understood to have told Sandro that they will not stand in the way if he wishes to move on and leave Turin this summer, although having turned down a substantial bid for him, it would seem the Bianconeri would prefer him to remain at the club. "But if Alex Sandro receives a salary offer which isn't logical for us, then..."
The news comes a fresh setback for Conte who was already making headlines for being reportedly frustrated at Chelsea's lack of investment in the transfer window so far, informing the club that he was open to leaving this summer.
The Guardian also report that the relationship between the 47-year-old and Chelsea's board has been put under increased strain, following his decision to inform Diego Costa that the striker would not be in his plans next season. "Players are masters of their own destinies".
Juventus are set to chase Benjamin Mendy to replace Alex Sandro.
