The 29-year-old would be keen on leaving City in a January loan move in order to get regular first-team football.
“Well I’m never going to be able to say how frustrated I am, some people might never understand but obviously I know it is part of the game I’m working hard in training and I just have to keep going,” he told Sky Sports News.
“Obviously it’s very important (to be playing first team football) but I know everybody’s time comes and goes and it will always come back again and my time’s going to come back again and I know what I’m capable of, I know what I can bring to the game for club and country so I just have to be patient and just be ready when my run of games comes.
“For the City fans I would never want to ever leave them permanently so I said I would always come back and that’s where I would like to finish my English football career at some point so as for leaving them fully, I would never consider it so it is just a matter of getting games really.”
