The Sunday Mirror says a record 39,000 season tickets have now been sold for the redeveloped 54,000-capacity Etihad.
Another 2,500 supporters who made a £100 downpayment last season on a season ticket are expected to swell that number.
And those figures are likely to get another boost if City get to unveil £150million of new signings.
A club insider said: “Season ticket sales have gone brilliantly and we are likely to have a 50,000-plus average crowd for the first time in our history.”
