Lescott was a regular member of Roberto Mancini's team during their Premier League title-winning campaign in 2011-12 but has been unseated by Matija Nastasic in recent months.
The 30-year-old, who partnered John Terry at Euro 2012, was initially left out of Roy Hodgson's squad to face San Marino and Montenegro but received a call-up after Michael Dawson and Rio Ferdinand withdrew from the team.
"If you'd asked me last year what my chances were of making the World Cup  squad then I'd have said, 'Yeah, pretty good,'" Lescott told reporters. "But you don't know. If I can play more regularly at club level then I think I'll be there.
He added, "Towards the end of the season, I'll address that [situation at City]. But for now, I'm fully focused on England and what England need to do."
Lescott was confident that his lack of playing time would not be a problem if he is selected to face Montenegro on Tuesday having completed 90 minutes against San Marino.
"I haven't been playing as much as I'd like of course but I have confidence in my own ability," he said. "I haven't been injured because I haven't been playing and I feel sharp enough to adapt to anything they offer."
