Arsenal have confirmed terms have been agreed for France international midfielder Samir Nasri to move to Manchester City.
Nasri has been chased by City in recent weeks and Roberto Mancini had been anxious to finalise a deal for the former Marseille youngster, who was in the final season of his contract at Emirates Stadium.
Manchester United reportedly had a bid rejected earlier in the summer, but Nasri is now on his way to the Etihad Stadium.
Reports over the weekend had suggested the deal had fallen through and Gunners boss Arsene Wenger subsequently claimed Nasri was happy in North London.
He had featured in Arsenal's 2-0 defeat by Liverpool on Saturday and trained with the squad on Tuesday ahead of the UEFA Champions League qualifier with Udinese.
However, with the Gunners due to fly out to Italy on Tuesday afternoon, the club have now confirmed that Nasri is on the verge of signing for City.
A club statement read: "Arsenal can confirm that they have agreed terms for Samir Nasri to move to Manchester City.
"The 24-year-old midfielder, who has spent three years with the Gunners, has been omitted from Arsenal's squad which flies to Udinese this afternoon and instead will travel north for a medical.
"The move will be subject to Nasri passing a medical and formal registration processes."
Had Nasri travelled with Arsenal and featured against Udinese, it would have rendered him ineligible to play for City in the group phase of the Champions League.
Speaking after Sunday's 3-2 win at Bolton, Mancini suggested that such a scenario could have led to City ending their interest in the player.
"For 40 days I've hoped in two days, three days (it would be done), I don't know why we haven't closed it," said the City boss.
"It's a big problem (if he plays for Arsenal against Udinese) but I'm sure we can close in 24 hours, maybe 48. For Nasri it will be important he can play in all the Champions League matches."
City have reportedly agreed to pay in the region of £24million for Nasri, who is out of contract at the end of the season and has refused to sign a new deal.
That has ultimately forced the hand of Wenger, who insisted earlier this summer the midfielder would not be sold and must now weigh up bringing in reinforcements after also losing former captain Cesc Fabregas to boyhood club Barcelona.
