Mancini is wrong, Nasri's red card for Bassong butt was a textbook call
22:30 GMT, 30 December 2012
Manchester City manager Roberto Mancini has no case when defending Samir Nasri as referees have clear instructions for such incidents as occurred two minutes before half-time in the game at Norwich.
Following a strong tackle by Norwich defender Sebastien Bassong on Nasri, the City player jumped to his feet and placed his head in his opponent's face.
When two players go head to head this is viewed as adopting an aggressive attitude to one another and if they go no further the advice is a caution for each player.

'Incredible': Roberto Mancini raged at the decision to send off Nasri but not Bassong
However, if, as Nasri did, a player pulls his head away and returns it, this is defined as a headbutt, which has to be seen as violent conduct and the offender sent off.
Mancini, who has already been asked by the FA to explain his criticism of referee Kevin Friend following the defeat at Sunderland on Boxing Day, hit out at referee Mike Jones.
The City boss said: 'Both players went forward with their heads, so if you are to send off one you have to send off both.
'There are two rules for different teams and I hate this in football and cannot accept this.'
However, with Jones cautioning Bassong after consulting with his assistant as well as dismissing Nasri it was textbook refereeing.
