The striker is on loan at Sao Paulo and has scored 26 goals in all competitions in 2015, but will return to his parent club at the end of the year.
Corinthians are eager to offload Pato - who they recently valued at €25 million - due to the burden of paying his sizeable salary.
Reports on Friday suggested that the Brazilian side had agreed a deal with Liverpool, but the Anfield club denied any approach to Goal.
De Andrade also told Globo Esporte that this was not the case but confirmed the player's agent has been talking to European clubs.
"Yes [I'm praying to sell him]. We know how difficult it would be if he were to return. I'm quite sure [he will be sold]," he said on SporTV.
"Corinthinas have not been approached by any club asking about the cost of Alexandre Pato.
"His agent is working with some clubs in Europe, making inquiries so that we can sell. It is being very well received.
"He has a market, is a great player, is 26-years-old - he meets all the requirements to play in a big club. I'm certain he will be sold."
