Chairman Bill Kenwright supported his manager, adding: "There is no pressure on David to sell anyone. Any decisions are his and his alone."
Chief executive Robert Elstone said: "As a club, we have publicly stated - as recently as Wednesday night - that we do not intend selling any players.
"David Moyes' primary focus is on building a squad so that we can continue to compete effectively in what is the most competitive League in world football."
Lescott has had three successful seasons at Everton since joining from Wolves in a £5m deal but City are homing in on him as their next big-money buy after landing midfielder Gareth Barry from Aston Villa, Blackburn Rovers striker Roque Santa Cruz and £25.5m Carlos Tevez.
Moyes, backed by Kenwright, is ready to block any offer and the crucial move may lie with Lescott and whether he prefers the greater riches on offer at Eastlands.
Moyes will also be reluctant to weaken further in central defence, with Lescott's fellow England international Phil Jagielka not expected to return until November after knee surgery.
