Deschamps joins Mancini: Man City's Nasri hasn't been good enough
Having already been criticised by City manager Roberto Mancini, Nasri has also copped pelters from Deschamps.
"Why is he not playable? The question now is different to when he was injured and played very little. I know what he is capable of doing.
"He is much less efficient than last season. He knows it too," said a straight-talking Deschamps.
