The Brazilian defender has been at Paris St-Germain since 2012, but has been linked with a move to Serie A champions Juventus.
The 32-year-old confirmed that he wants to stay at the club, but says that this is something that he ultimately won't decide.
"It's not for me to decide, we need to talk," Thiago Silva said.
"We started talking last year, at the end of the season, and after it stopped, I do not know why.
"But I'm happy here, I want to stay, extend my contract. We need to talk with the president to know what we will do in the future".
Thiago Silva has been in the French capital for four years and has won four consecutive Ligue 1 titles.
