The versatile defender is still only 25 years of age, so time remains very much on his side.
He was, however, handed a senior international bow in 2006 and has gone on to collect just 13 caps in seven years.
Injuries have held him back on a regular basis, with his latest return to action coming in City's 5-0 Capital One Cup thumping of Wigan Athletic on Tuesday.
Richards believes a place in the England squad is achievable if he can stay fit and earn a regular role at club level, but concedes that others are ahead of him in Roy Hodgson's pecking order as the Three Lions chase a spot at next summer's World Cup in Brazil.
He said in The Sun: "I've been stuck on 13 caps for some time now - unlucky for some!
"I'm not sure what the answer is. I just need to get fit and play regularly.
"Danny Sturridge is an important player for England but he should have been playing for the last four years - he's a real talent.
"It's all about opinions but I hope Roy Hodgson will give me a chance.
"I want to go to Brazil in 2014 as much as the next man and as I can play right-back and centre-half, I can give the manager some options. But I can't help thinking that unless there are injuries, it won't happen.
"Picking up niggling injuries isn't helping so I need to keep fit, do my best and see what happens."
Richards added on his frustrations at club level, which have seen him spend too much time on the sidelines: "It's been annoying because Matija Nastasic was out and then so was Vincent Kompany, so it would have been the perfect time for me to slot in at centre-back.
"Having said that, the manager didn't play me there in pre-season so maybe I'll only play at right-back.
"I've had niggling injuries at the wrong times and it can be frustrating because I know I could have done a job if I'd been asked to.
"We have some great central defenders at the club with Kompany, Nastasic and Joleon Lescott and we also have Martin Demichelis now so I can't see when I'll get a good run in central defence.
"Right-back is more realistic. We'll be playing two or three games a week and it's not physically possible for one player to keep up that sort of pace. Right-back is where I need to concentrate on."
