The Brazilian striker has had his fair share of fitness problems in 2010, but would like to reassure the fans he feels in good shape.
"I am improving every day," Pato told Sky Italia. "I am satisfied with what I am doing at Milanello. I am certain that I will be here to play in the first game and do well.
"I am not 100 per cent, but I am satisfied with the work that I am doing. My season will be like the others.
"I am concentrating on my job to always do better because I want to win everything at Milan, not by myself but as a team."
