Cavani heaped praise on his fellow Uruguayan earlier this week before Pellestri's arrival in England.
Now after his first United training session, the former Penarol starlet told manutd.com: “It's unbelievable and fantastic to hear such comments from the players they were, and are. Cavani is going to be a team-mate of mine. So I'm very glad and happy to hear those comments.
“Cavani is a top player and I think he will be a great player here also."
Pellestri has also identified areas in which he wants to adapt his game, and believes playing under Ole Gunnar Solskjaer and coaches Michael Carrick and Kieran McKenna will only be a benefit in the long run.
“I want to improve, for example, in shooting, passing the ball. All those things that make you better on the pitch.
“There are lots of people in charge of you to help. I think that I should learn from my team-mates and the coach, because it's the first time I'm here in England. I will need help from them."
