"My desire from the start was to begin this adventure. I can't wait to get started and to put myself at the disposal of the Coach and my teammates," said the man who'll wear the Number 6 jersey.
"I am happy to be here and watched Sampdoria's win over Milan last week. The team got off to a great start, as not everyone can win at San Siro.
"There are many young and talented players here, especially in midfield. My years abroad have helped me to grow and I will try to bring that experience to the others."
