Silva reiterated this to week to AS that he would be leaving Manchester City at the end of this season.
His contract will be expiring next month, although it is believed he will sign a short-term extension so he can finish the 2019/20 season at City, per ESPN.
The 34-year-old is not short of offers, with clubs in Major League Soccer and Japan hoping to sign somebody of his enormous stature.
An emotional homecoming to Valencia, who Silva left for City 11 years ago, has also been mooted.
Angulo played alongside Silva at the Mestalla, and the club's Juvenil A coach hopes his friend decides on a reunion with Los Che.
He told Tribalfootball.com: "I believe he is very well regarded in Spain and he won many titles with the national team. Yes, I would like to see him playing again in Valencia in the final years of his playing career.
"He's a lad that I appreciate very much and I have maintained my friendship with him. It would be a luxury for Valencia CF to count on a player of his great quality once again."
Silva won four Premier League titles, five League Cups and two FA Cups with City.
He also won the World Cup and the European Championships in 2008 and 2012 with Spain.
And Angulo says the 'attacking midfielder' defined an era in the Premier League.
"I believe that Silva is a player that has defined an era in English football for his style, his talent and his capabilities," added Angulo.
"He also is a player who started with Valencia at a very young age and came through the ranks of the Academy.
"Watching him back then, it was clear to the trainers at the Academy that he had a great potential future in football …a left-footer with great control of the ball and with ease on the ball too…and an excellent final pass."
