Jean Michael Seri, who was named in the official 2016/17 Ligue 1 Team of the Season, was reportedly close to joining the Blaugrana and was left heartbroken when he found out the deal had collapsed.
With the player later voicing his frustrations, blaming the French club for the failure of his "dream move", Nice president Jean-Pierre Riviere has now insisted it was Barcelona who pulled out of the deal.
"On Wednesday morning, Julien Fournier (Nice's managing director) called me early, at 9, and said, 'Jean-Pierre, I don't understand. I just got a call from Barcelona, they told me they're stopping with Micka (Seri),'" he said, as quoted by ESPN.
"In the afternoon, I got hold of (Barca president) Josep Bartomeu, a little embarrassed, who told me: 'Jean-Pierre, it's the first time that this has happened to us, but our technical staff have decided not to do Micka Seri. It's absolutely not a problem of money.'
"On the Thursday morning, it was confirmed definitively: they won't be going for Micka Seri.
"And it's then that things go off. I said to Barca, 'You have messed up one of my players,' because there was a contract ready. I put myself in the place of Micka: it's his dream to go to Barca, and overnight it's broken."
