"I've been aiming to win this competition since I was a child," Cancelo said. "I came here because it's my type of football. Man City is one of the teams that can win the Champions League."
Cancelo has previous experience of Gian Piero Gasperini's side, having faced them with Juve in Serie A.
"I believe we are both strong teams, all the teams in the Champions League are strong teams and I believe it will be a lively, interesting match," he said.
"I hope we will get the three points because if we get up to nine points it will put us in a secure position in the group."
