Sources close to City were last night adamant they will slap in a "take it or leave it" offer for Arsenal's French midfielder.
And SunSport understands there is growing confidence that Gunners boss Arsene Wenger and his board have accepted they are fighting a losing battle to hold on to the unsettled star.
City officials have been given encouraging signs that Arsenal finally want to bring things to a head and are reluctantly ready to sanction a deal.
There were even suggestions a move could be rushed through by the weekend, giving Nasri an outside chance of featuring in City's Community Shield clash with Manchester United, who also like the 24-year-old.
The big choice for Arsenal is whether to cash in now on an unhappy Frenchman or lose him for free when his contract expires next year.
Nasri insisted in October he would have signed a contract when there was talk of a new deal to keep him at the Emirates.
But he grew increasingly restless when nothing transpired and he is now ready to join the City revolution for £125,000 a week - just £10,000 a week more than he could pick up at United or Arsenal.
buy... show us the power of money.. another blues revolution..
