Villa chief Paul Lambert is reportedly plotting his targets to bolster the Villa Park squad at the end of the season on the basis they win their battle to avoid relegation to the Championship.
And it appears a raid on City is Lambert's main priority to ensure there is no repeat of this season's struggles in the Premier League next term.
Sinclair has endured a miserable time at the Etihad Stadium, where the 23-year-old winger has made just two Premier League appearances following his £6.2million move from Swansea.
He is likely to depart City in order to gain some regular first-team action and Villa could try and snap him up on a cut-price deal at the end of the season.
Lambert is also looking to bolster his inexperienced defence having lost veteran Richard Dunne to injury all season. And that would pave the way clear for him to make an offer for Lescott, who has struggled for a place in City boss Roberto Mancini's first team this term.
Lescott has hinted that a move away from City may be necessary if he wants to keep alive his hopes of playing in next year's World Cup finals, should England qualify.
However, Villa are likely to face stern competition from the likes of Newcastle and his former club Everton to secure his signature.
