Nasri's uneasy relationship with the national side worsened on Tuesday when he failed to even make the reserve list for Les Bleus.

"Let's just get this straight! I'm not mad i get my bf [boyfriend] for 2 months.... I just think there's a level of respect to be had!"
Nasri scored the winner in the Capital One Cup final and City's title-clinching goal against West Ham United on Sunday.
His girlfriend is the latest spouse to defend their footballing other half after Lisa Carrick insulted Roy Keane for his critique of Michael Carrick's performance following Manchester United's defeat to Olympiakos in February.
"Roy Keane what a **** says anything to provoke a reaction.. That's all.. Done," Mrs Carrick said, before deleting her tweet.
