Galli oversaw a bounce game between the first team and youth players yesterday, which featured Pato and also fit-again Ronaldo, and was full of praise for the young striker.
Galli said: "Since he arrived, I have always seen Pato working hard in training. He has goals inside him, and beyond this is a player who works hard for his teammates, it is always something important for the team.
"It is not easy to find players of this calibre. Obviously, we are talking about seeing him in training, but also in other games played against the primavera team, or with other clubs, he has proved to be an extraordinary player."
