Nasri was first contacted by the club last autumn about signing a new contract but talks have progressed slowly.
Although the Frenchman has been offered better terms than other high earners at the club, including Robin van Persie and Andrey Arshavin, his camp have pressed for the midfielder to get similar terms to Fabregas, who earns £110,000-a-week after his contract was renegotiated two years ago.
It is understood that the main details of the contract, which is believed to be for five years, have been agreed and both parties are confident a deal will be finalised by the end of the season, although the basic figure will be bolstered by bonuses and image rights payments, and possibly a signing-on fee.

“There is no suggestion that Nasri wants to leave,” an Arsenal source told Goal. “He has told the club he is in no rush to sign a new deal and believes he will be in a stronger bargaining position if he wins one of the player-of-the-year awards.”
It has widely been reported that Nasri’s current contract ends in 2012 although this has been disputed by other sources, who believe Arsenal would never allow themselves to be in such a vulnerable position.
If his deal runs out in 14 months, the Londoners would have little bargaining power if a European superpower were to come calling as Nasri, who joined Arsenal from Marseille for £12 million in 2008, would be able to leave for an even smaller fee.
Although his form has dipped since Arsenal’s League Cup final heartache - he has not scored since January 19 - the midfielder has been the club’s outstanding player in a season in which he has scored 14 goals and become a far more influential player in the team.
Arsenal’s transfer spending does not compare to that of their rivals, but the wage bill, which has risen by £20m over the last two years, was £110.7m in 2009-10 and is expected to soar beyond £125m this season. Only the wage bills of Chelsea, Manchester United and Manchester City are higher.
Chief executive Ivan Gazidis has described the effect of player wage inflation as meaning that Arsenal effectively have to bid to keep their own players.
