The Daily Mail reports that Pato remains on the radar of several top-flight teams, including Chelsea and United.
The 26-year-old has scored 10 goals while on loan at Sao Paulo in brazil last season.
The Brazilian striker’s contract with Corinthians is set to expire in December.
Pato told Mail on Sunday last month, that he was interested in a move to England: “One day I knew I would like to come to England because I think the championship is the number one in the world. It is very competitive.
“I like the emotion in the English league. You look at the TV and you see the stadium and the fans. I remember that when we played Arsenal, they were very strong and very fast. My special thing is my speed. I’m fast. I think that’s good because the football here is very quick.
“I don’t think the physical part of English football would be a problem. When you get the ball, you need to be ready. The defenders here are very tough but I like that.
“I have spoken to Willian, Firmino, Coutinho and David Luiz before. I think Brazilian players can play here. You mix talent and intelligence and Brazilian players can play here.”
