The 18 year-old attacker is full of praise for the Italian.
He told Globoesporte: "It's an excellent relationship. He gave me all the freedom in the world to play football, to be myself. To feel that affection, to feel everything he represents, to have opportunities with him... it's incredible.
"I learn more every day, I try to learn a lot from him. He's a very intelligent coach, someone who always wants the best for us. So I'm making the most of it.
"Great, it's really great. It applies to everyone. He's a guy who's won almost every championship possible and has worked with countless quality players. He has the humility to learn Portuguese, to be with us, to talk with us, to debate.
"It helps us improve even more. To have that humility to know that we can improve, to know that we can play. So, I think it's really great,"
