Samir Nasri has slammed the 'stupid' fans who booed Raheem Sterling during Manchester City's International Champions Cup clash against AS Roma at the MCG.

Sterling has been vilified by many following his conduct in forcing a move from Liverpool to City but surprisingly, the winger was roundly booed on his debut even by the fans inside the Melbourne venue during City's pre-season clash with Italian club Roma.

Former Arsenal midfielder Nasri, who is no stranger to abuse from the fans, has been left disgusted by the treatment of Sterling and has stated that people need to respect his decision to leave Liverpool.

Nasri told reporters: "You always have stupid fans in the stadium. The same thing happened to me when I left Arsenal. You have to move on. He has come to Manchester City and you have to respect his decision.

"We just have to let him play and he will show how talented he is. We didn't expect anything like that from these fans, so it is a little surprise. But if he needs any advice about that, then he can come and talk to me."
