Pato made his comeback in victory over Genoa.
"I am alive again," smiled the Brazilian. "I played, I ran, I sprinted and I didn't feel any pain. I am so happy.
"I like to play and to do well, so it was a very important evening for me. I was able to do everything and felt no pain, so I feel good.
"Unfortunately I didn't manage to score, but I tried to help my teammates. I hope to score soon, hopefully in the next match."
