Contract rebel Samir Nasri today labelled Arsenal fans as "disrespectful" after chanting against him at Newcastle on Saturday.
The France midfielder, 24, has yet to pen a new deal with the Gunners, and so could leave on a free transfer next summer.
Nasri has been linked with a £25million move to Manchester City, although Arsene Wenger remains hopeful the playmaker will stay, particularly after the sale of captain Cesc Fabregas to Barcelona.
The 24-year-old did not feature in the opening Barclays Premier League game at St James' Park because of illness, but was the subject of abuse from some sections of the travelling support, who questioned his loyalty and labelled him greedy.
Nasri, who is suspended for tomorrow night's Champions League play-off first leg against Udinese at Emirates Stadium, used his Twitter account to hit back.
He wrote: "I heard what the fans were singing about me on Saturday and it is really disrespectful because I'm still a (sic) arsenal player."
