The fullback joined over the summer from Parma.
“The feelings are positive, I'm enjoying myself," Darmain told Sky Sport Italia. “I knew the coach well, we worked together in the national team.
“It was easy to adapt and now it's up to us to do our part better.
“The coach demands a lot every day, he takes care of every detail and at this level these things make the difference.
“He always wants to win and passes it on to the team."
