Silva is beginning to show his best form in a City shirt.
He told the club's website: “Everything has been made so much easier by the way I’ve been treated so well by my team mates and everyone here at the club who has given me a helping hand.
“Moving here was tough to start off with, it was difficult physically, the speed of the game was different and I had to adapt to a different lifestyle. The language was a problem, even when playing, but things have gone very well for me since. The weather’s gone a lot colder but I don’t mind it because everything else is going so well for me.”
