Garcia left Barcelona for City last year.
He told Marca: You don't think about how it would be somewhere else. I'm very happy with the opportunities I've had.
“I'm in my third season in Manchester already and I'm very happy. At first it was more complicated, but then I adapted after a few months. I'm lucky to have a lot of Spanish team-mates, who make things easier.
“When I first went, I was hoping to see how things were going. We all know the Premier League is a different league, it's more physical. I was going to see what happened but I'm very happy with how it's gone.
“At the end of last season, they told me I'd start pre-season with the first team, and I did. I'm one of the first-team players. I train with them."
