Juventus have again insisted that midfielder Paul Pogba will not be sold during the summer transfer window.
A target for Barcelona and Chelsea, the Frenchman has an estimated market transfer value of £71m.
Director Giuseppe Marotta has confirmed that the Spanish giants have made an approach to sign the 22-year-old but also that the club has no intention of selling one of their best players.
"Whoever is interested needs to talk to us and not with agent Mino Raiola," Marotta told Mundo Deportivo.
"Barca cannot make any signings and Juve does not want to sell.
"We have negotiated with Barca in recent months, [but] the player is not for sale.
"We have done so in a serious and correct manner as it should be between two teams that have a lot of history and importance in world football.
"The situation is very clear between Barca and Juventus after the meeting we had in Milan.
"Barca made an offer and we replied."
