However, Spaniard insists that he did not have to think too hard when making his switch to Eastlands as the club were persistent in pursuing him and made "a very interesting offer"
The Spanish club were widely thought to be on the brink of a meltdown due to mounting debts and were forced to sell their stars to reduce the burden that had weighed down the club.
Prior to Silva's £27 million move to Eastlands, David Villa was sold to Barcelona for a fee believed to be in the region of £35m.
The World Cup winning midfielder has conceded that he was forced to leave the Mestalla due to the club's financial predicament and would not otherwise have sought a move away.
"Why did I leave Valencia? Because the club needed me to," Silva said, according to The Telegraph.
"I was happy there and wouldn't have left, but the situation the club was in demanded it.
"It was a big injection of money and it was good for them. My life has always gone step by step. It was time to take the next one.
"City showed a great interest and I wanted to settle it quickly. It was a very interesting offer, a good club, and I didn't have to think too much."
