The Brazilian defender admitted speculation of coach Carlo Ancelotti heading to Real Madrid is unsettling, but will not decide whether or not he wants to remain in Ligue 1 until Ibrahimovic – who joined with Silva in a double coup from AC Milan – returns from his holiday.
"Since I've been in Brazil, I haven't spoken to Ibra on the phone," the 28-year-old told Sky Sport Italia.
"He's on holiday and I'm making sure to leave him be because he should be relaxing. I don't speak that often with him, but when he gets back from his holidays we'll surely talk about our future because it's something that's very important to us.”
Silva, a reported target of Barcelona, added: "I've always spoken with Carlo about my plans, because I came to Paris Saint-Germain largely for him and [sporting director] Leonardo.
“So the doubt surrounding him at the moment is hard to take. I hope that an agreement will be reached as soon as possible, because the situation is tough for us players as well.
“We're hoping that next season we'll still have a strong team capable of fighting it out in the Champions League."
Silva’s agent recently insisted that any transfer talk is false, and that the 32-times capped Brazil international will remain in Paris for 2013-14.
