Milan sealed the signing of Silva from Porto on Monday in a deal that could reach a value of €40 million.
Bacca's agent Sergio Barila would not rule out the possibility of a move to PSG when asked about his client's situation.
"PSG? These days Ligue 1 is one of the best European leagues and Carlos wants to continue in Europe at a good level," Barila told FootMercato.
"He has had offers from outside Europe, but he told me that those don't interest him. He cares about the sporting side.
"The economic side is not a priority for him at this time, even though there are non-European markets where big investments are being made.
"We are calm at the moment and we have not talked about anything with Milan for now.
"He is at Milan. If the club feel they need a new striker… there will be more competition. The transfer market has just started and no one knows what is going to happen in a long summer.
"The player has three years of contract with Milan. He wants to play as many matches as possible.
"He has been asked for by several big European clubs and we will study everything quietly."
