The 29-year-old England international has missed City's last five matches after suffering a groin injury in the Europa League defeat away to Portuguese side Sporting Lisbon last month.
But Lescott tweeted Tuesday: "I'm defo fit now been back training for 4/5 days now, so I will be available for selection on the weekend."
During his absence City -- bidding for their first English title since 1968 -- have lost at Swansea and drawn with Stoke and Sunderland.
Those results have contributed to City conceding the lead in the title race to local rivals and reigning champions Manchester United, who could be eight points in front by the time Mancini's men kick-off at Arsenal.
