Corinthians sporting director Edu, who signed Alexandre Pato for the club in 2013, believes the Brazilian can succeed at Chelsea should he adapt to their philosophy.
Pato resurrected his in South America, after injury problems saw him lose form at Milan.
His first season was a success with Corinthians, only for his second season to be a mirror of his debut and he was eventually loaned to Sao Paulo.
Pato got his form back and attracted major interest, with the striker joining Chelsea on loan.
And Edu, who won two Premier League titles and three FA Cups with Arsenal and is now sporting director at Corinthians, believes he has what it takes to shine in England.
“Injuries are not a problem any more. We did a good job with him here and he improved a lot on the pitch,” the 37-year-old told The Sun.
“I think he can be a success in the Premier League. Everyone is disappointed with how it turned out with Pato.
“But he has no injuries, so I think he will be good for Chelsea. He could play in the Premier League for many years.
“It is hard to compare him to other players but he is a big talent. He has matured. Maybe that can help him. He has changed in his mind a bit.
“I think he is mature enough now to understand this change at Chelsea. To be in the mentality of the club.
“Many clubs wanted him but the last word is the player’s word.
“When Chelsea came to talk to us and gave us the opportunity to start the negotiations, Pato said he wanted to go to the Premier League.”
However, Edu feels the attacker must adapt to the expectations at Chelsea.
“Pato didn’t get the philosophy here and what the fans expect from the players,” he added.
“He must get the philosophy of the club. He has to connect well with the supporters.
“That is what I mean about philosophy. If you see Manchester United, Arsenal or Tottenham, they have a traditional way of playing and the fans see that.
“That is what he has to understand, he must be clever enough to know how important that is now.
“At the beginning, Corinthians were prepared for him to play very strong and fast – like at the other clubs where he did well.
“He started well, was scoring goals and was playing games. But it was tactical as well, and in the end about the team. He didn’t suit us and then Sao Paulo wanted him and we wanted Jadson, so we changed them around.
“And it worked for both – for Pato and for Jadson – they both did well for their new clubs.
“In the end Sao Paulo was better for Pato, Corinthians went for another player and we changed. Both sides did well.”
