|11/1||Joleon Lescott is 11/1 with BetVictor to score at any time for England against Montenegro
"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.
"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 added. "I haven't been injured because I haven't been playing and I feel sharp enough to adapt to anything they offer."
