Silva has been linked with a move to the Premier League champions.
He said: “It’s an honour for any player that a club of the prestige of Manchester United should follow them and that in itself is enormous praise.
“I know that the Premier League is a big competition and hard to resist.”
He added: “I am committed to Valencia and my dream is to win the title but in the future anything is possible.
“Valencia have rejected offers for me in the past few months and I am happy here.”
