Juventus director Pavel Nedved has welcomed their new additions.
Nedved said, "It's special to be here. All the players feel it from the first day. Ronaldo? Juventus' step forward among the big clubs in Europe has been confirmed further.
“That we managed to bring Ronaldo to Juventus is something exceptional. It'll give us a bit more for the future, as well as for all of Italian football.
“Emre Can? There was very little talk about him, but he was an important signing by the board.
“All the big clubs in Europe wanted him and we managed to get him. He's a player who gives a lot of substance and is perfect tactically and technically.
“He's a typical German who knows how to use the ball well. You'll see that he'll be very important for the team.
“Cancelo? He's an important signing too. I've seen only a few players join Juve with his character, technique and vivacity. I think he'll be important this season, especially in Europe.
“Our objectives never change. What counts for us is to win every game, we want to show it from the match against Chievo."
