Neville and Tevez escaped FA punishment

Gary Neville and Carlos Tevez have escaped punishment from the Football Association, but have been warned that their row cannot continue.

Neville was under investigation for a one-fingered gesture that took place in United's 2-1 loss to City on Tuesday.

Tevez called former team-mate Neville a "boot-licker" and a "moron" for his comments about the Argentine before the Carling Cup semi-final first leg.

However, both players have been warned about their future conduct by the FA.

It is understood if the players were to be formally disciplined in future the FA reserves the right to refer to Neville's conduct and Tevez's words.

In slightly different ways, both Ferguson and Roberto Mancini tried to calm the situation on Friday.

But the FA has been in touch with officials from the red and blue halves of the city as well.

And Neville and Tevez have been warned that any repetition will bring punishment that also takes into account this week's indiscretions.

That would include any negative comments in pre-match interviews, or any poor on-pitch behaviour.
