The former PSG midfielder has joined Juve in a Bosman deal.
“Juventus are a great club with history and prestige," the midfielder told JTV.
“I'm very happy to be here. One of the reasons that led me to choose Juventus is that I wanted to improve and take my career to the next level.
“I'll be playing with some excellent players. There's no better place to grow and keep learning.
“I'm left-footed and I like doing a bit of everything. I feel like an attacking player and I like to attack, but I also like to defend. Like we say today, I'm a box-to-box player.
“I talked to so many people before coming to Juventus, including Buffon. He knows this club well, and he told me about what life was like here.
“It's always very important to ask for advice when making a decision. It was nice to receive compliments from Gigi and I sent him a message thanking him.
“He replied that he was only speaking the truth."
