Manchester City midfielder Samir Nasri and Arsenal's Emmanuel Frimpong will escape any punishment from the Football Association over an altercation after last night's Carling Cup quarter-final.

The former teammates are believed to have come to blows in the Emirates tunnel after City's 1-0 win over the Gunners last night.

The apparent incident was not reported to the FA and will therefore not be reviewed by the governing body.

Roberto Mancini's side claimed a place in the final four yesterday along with Liverpool and Cardiff City.
