The Bianconeri chief has confirmed the offer from the European champions, but has stated that the bid has been rejected.
Representatives from the Catalan club were rumoured to be travelling to Turin this week for a meeting with their Bianconeri counterparts, which has been confirmed by the Italian supremo.
Following the consultation, Marotta has revealed that the reigning European champions have made a blockbuster offer for the France international midfielder - but Juve do not want to sell their prize asset.
“The mood of the meeting was very good, terrific, but we did not reach an agreement for Pogba with Barca,” AS quote Marotta as saying.
“We received an offer of €80m but I can say that Juve do not want to sell Pogba.”
The report suggests that Barcelona, who are currently serving a transfer ban, wanted to sow up a deal that would bring the former Manchester United man to Camp Nou in the summer of 2016.
With Andrea Pirlo’s future at Juventus a source of speculation, it is clear that Pogba is a critical member of Max Allegri’s side.
The young Frenchman is widely acknowledged as one of the most promising players in world football, with a host of leading European clubs being linked with the star over recent months.
Pogba featured in the Champions League final for Juventus against Barcelona, but was unable to prevent his current employers being beaten by his suitors 3-1.
