Man City favourite Zabaleta: I've surprised myself
The fullback's current status is not something he anticipated when he arrived from Espanyol.
He said: "When you sign a for a club you just try and do your best but I admit that I didn't know whether I would be still be in the squad and winning trophies five years later because it was a different club when I joined.
"So I am very pleased to be a part of this club, I'm really happy to be here.
"Obviously as players we need to keep working hard to keep our place in the team because in every position we have two or three players of real quality so you have to work hard."
