Silva, whose PSG side play Chelsea in Paris on Tuesday evening, thinks his acquisition can be a vital one for Chelsea. Speaking to the Daily Telegraph, he said, ""I know him very well; he’s my friend," Silva says. "We played together at AC Milan for three years and Pato has incredible quality. He’s been through a lot of difficulties and it is good to see him back in Europe.
"I think he can make the difference for Chelsea, I really do. Because he is strong on his right foot, his left foot and he is quick. Very quick. That’s why I think Chelsea have made a good choice.
"It’s difficult as a player once you have gone back to Brazil to get that second chance in Europe. Sometimes you only get one chance. I think European clubs need to see exactly how you play. But I think he had a really good season with Sao Paulo [on loan] and that’s why Chelsea have taken him because he’s a really great player. Believe me."
Silva also praised PSG teammate Angel di Maria, who only survived one season in the Premier League before joining the French champions last summer, "With Di María the problem was that he did not have a lot of opportunities to play in the English league and it is very different from all the other leagues.
"I think when you come into a team you need a group that is going to help you to improve your game and that did not happen at Manchester (United) and he was also injured a lot, so he really did not get enough opportunities and he lost confidence.
"Here his confidence is really high. At PSG he is that player who can make the difference. Everyone says that Paris is magical but here is a player who is magical and in Di María, even if we have got Zlatan, he will make that difference."
