The midfielder was impressive with Sassuolo in Serie A, but after being sold to L2 Paris FC this summer, he admits he was unhappy there.
He told RMC Sport: "I broke down a wall... Players, we all have our own egos but what do you want to do? I arrived in Ligue 2 without any expectations.
"My departure from OM in 2021 was due to sporting aspects. With (Andre) Villas-Boas I didn't play much. He put me on the pitch as a right striker and it didn't make sense.
"I was 22 and I had to make a choice. In Italy in terms of atmosphere, Sassuolo was horrible. At Fiorentina, however, I found some aspects of what I was missing in Marseille. They invested almost 120 million (euros) in the training center, there was pressure and enthusiasm."
