The pair are likely to spearhead Milan's attack for the next three games after Zlatan Ibrahimovic's suspension.
“I wanted to play with Antonio for a while and now I can do it,” Pato said. “I am happy. I only want to play, with or without Ibrahimovic.
“I can either play as a centre-forward or as a second striker, it depends on the Coach's decision. I want to show my worth.
“Ibrahimovic is fundamental for us. It's a big loss, but we have champions who can play well.”
