Juventus chief executive Giuseppe Marotta has insisted that neither Paulo Dybala nor Paul Pogba will be allowed to leave the Italian champions this summer.
Dybala has been strongly linked with a move to Barcelona after hitting 16 goals in 33 appearances for the Old Lady since joining from Palermo last summer.
Pogba, meanwhile, is believed to be a long-term target for the world's biggest clubs, including Barcelona and Real Madrid.
Both players are expected to be the subject of big-money bids at the end of the season, but Marotta has claimed that Juve will reject any interest that arrives.
"Juventus are in a position where we can reject all approaches for Paulo – and we have already done that," Marotta told Gr Parlamento.
"He will become even better when he gains more experience, but he is already a top player right now. Selling him is not even an option for Juventus.
"And the same goes for Pogba. He is an important player for us. We want to keep winning in Italy and also make an impact in Europe."
Juventus struggled for form at the start of the season, but have won their last 15 in the Italian top flight and returned to first place in the Serie A table with a 1-0 victory over Napoli at the weekend.
