The Wales striker said: "I had a loan spell at Norwich last season and that worked well, I scored a few goals and got some experience.
"But I am back at Manchester City now, and with a new three-year contract, so I am really pleased with the way things have gone. For me to maybe win my first full cap for Wales this week either in Iceland or Holland would be the perfect end to a great season for me.
"When I go back for pre-season, I will be firing on all cylinders and trying to impress whoever is the manager by then."
He added: "I am not worried by what has been going on at City, there is nothing I can do about it, apart from concentrate on my football and improving my game. It was a big step up going into the Championship on loan at Norwich, and since then I have been training with the first team at City. All that has got me into the Wales squad, it couldn't be better.
"It has made me proud and my family proud. A first cap would be a great moment. There are a lot of youngsters in this squad, a lot of us have come through with the Under-21s, so it is not as scary as it would be if I was just on my own going into the squad."
