Prior to Fernandez's comments, Seri attacked Nice, accusing his club of breaking their promise to do business with Barcelona for his agreed release clause - thereby putting the deal in real jeopardy. Barcelona were poised to activate his €40m (£36.8m) release clause following the conclusion of Nice's Champions League qualifier against Napoli, but the morning after that second-leg clash, it emerged the club had chose to suddenly end their interest in the player due to reservations held by the Barcelona technical staff.
Rivere though has hit back at Barca, laying the blame in Barca's court and accused them of "messing up" the midfielder.
Rivere said that on the Wednesday before the end of the transfer window he received a call from Julien Fourinier, general manager of Nice.
"In the afternoon, Bartomeu called me, a little embarrassed, and said to me: "This is the first time that it has happened to us".
Nice president Jean-Pierre Riviere has revealed that he received a phone call from an "embarrassed" Josep Maria Bartomeu to confirm that Barcelona were withdrawing from the deal to sign Jean Michael Seri. It's not a money problem at all'.
"On Thursday morning, it was definitely confirmed".
"Everything had changed. I told Barca, "you blew it for the player" because they had a contract ready for him".
Rivere added: 'I put myself in his [Seri's] shoes; it was his dream to go to Barcelona and then it was broken.
Seri, who amassed a combined 16 goals and assists in 34 league appearances last term, did not play in his club's final league game before the global break due to his disappointment over his proposed transfer not going through.
