The 30-year old centre-back was in and out of Roberto Mancini's starting line-up last season but is hoping to be given more chances by new manager Manuel Pellegrini in a bid to extend his Eastlands career.
"If he (Manuel Pellegrini) does call upon me then I'd like to say I'd give 100 per cent and do his decision justice," Lescott told talkSPORT.
"I'm in the last year of my contract now so I've got to get my head down and try and earn a new one here and remain here.
"It's nice to be a part of this club and it's nice to know that I came at the start when the club were in transition and as they started winning things.
"My ambitions don't change but now I'm full focused on being selected for Man City and then hopefully I can get back into the England squad for the World Cup qualifiers."
