Barcelona have been linked with the former AS Monaco midfielder all summer and could firm up their interest should Frenkie De Jong depart the Camp Nou.
Silva has been one of Manchester City's most outstanding performers since joining the club from Monaco in the summer of 2017, helping them win the Premier League four times, one FA Cup and four Carabao Cups.
"I've always said that I'm happy here, but I have no idea what's going to happen," Silva told ESPN. "We'll see, honestly.
"My relationship with the club is very honest. I've been open with them, and they know what I want.
"If I stay, I'm very happy, and I will always respect this club and give all my best. If not, it's football and we'll just see what happens.
"It's a big club, and they don't want players who are not happy at the club. They always say to all of us that if you're not happy, you can go.
"Of course, they are in business and they want the right amount of money for letting us go, but personally it's a relationship with the club that is very respectful.
"They have always been honest with me, and I have always been honest with them.
"As I said, I will always respect my relationship with Man City, with the fans, with the staff, with my team-mates, so whatever happens happens, and for sure, it will happen in a very respectful way."
Silva was a second half substitute when Man City started their title defence with a 2-0 win at West Ham United last weekend.
