Pato missed almost an entire season with muscular problems and has just returned to the field, but is lacking match fitness and sharpness.
"I am back after a long time, but in a way I never left. I have always been here working hard and am back playing on the pitch, which is what makes me happy. When I reach 100 per cent, everything will be fine.
"To those who say I am scared of hurting myself again, I reply that they don't know me. The only time I was ever afraid was when I was 10 years old and risked losing an arm.
"I have never felt so calm, as I am working well in a great squad with marvellous fans."
