Pep Guardiola uncertain about the Spaniard’s future.
The midfielder has been linked with a move to Camp Nou all this summer.
Silva has established himself as a crucial player in the Manchester City squad and helped them win four titles in the last five years.
Barcelona are interested in signing the 27-year-old despite their financial problems but they could only sign him if De Jong departs this summer.
Pep Guardiola wishes the Spaniard to prolong his stay at the Etihad but will let him leave if he wants a move.
“Sometimes you have to sell,” Guardiola said. “For the desire for the players, I need people happy here, we try to do it together.
“I would love for Bernardo to continue here, a very special player in the locker room, but I don’t know what will happen. What happens will happen, if he stays is perfect, if he has to leave it’s because football is like this.
“Players have desire and I’m not a person to stop a person desire in life. Football career is so short. I’m a small part of the club, I have to speak to the club, they decide and I say okay.”
