The Welshman was officially unveiled by the Italian champions on Monday afternoon in Turin and he was quizzed on the responsibilities that come with wearing the No 8 shirt worn by Claudio Marchisio, Antonio Conte and Didier Deschamps.
"I wanted the No 8, I wore it at Arsenal and when it was free here I had to take it with both hands," Ramsey said.
"I know Marchisio was an unbelievable player, grew up here and had a fantastic career. I spoke to him a couple of times in J Medical.
"If I can emulate what he did for Juventus I would be pretty proud of that. I know it comes with responsibilities but I am ready for that."
He later added: "When I heard that Juventus were interested in me, I thought it would be a dream to come here, as well as a great challenge.
"You can't turn down this opportunity. This is the right club for me. I hope to be a part of the history.
"I think the squad and the players and the manager have all welcomed me very nicely so far. I have spoken to him (Maurizio Sarri) a few times.
"He is very approachable and easy to talk to. I am looking forward to helping my new team-mates. I am looking forward to the challenge and I hope to play my part."
