The Football Association have urged Arsenal boss ArsEne Wenger and Chelsea manager Jose Mourinho to end their recent war of words.
FA chiefs telephoned senior figures at both clubs yesterday to stress the need for the two managers to restrain their future comments after an unseemly public spat.
Mourinho had branded Wenger a "voyeur" who was supposedly obsessed with Chelsea after the Arsenal boss questioned whether the Blues had "lost a little bit of belief" with their draw at Everton and Carling Cup defeat by Everton.
Wenger responded by calling Mourinho's comments "out of order . . . and disrespectful", adding that "when you give success to stupid people, it makes them more stupid sometimes".
Neither manager is yet facing disciplinary action for bringing the game into disrepute but any further outbursts would almost inevitably carry the risk of an FA misconduct charge.
John Barnwell, the chief executive of the League Managers' Association, had also urged Wenger and Mourinho to bring their "tit-for-tat" exchange to an end.
Barnwell said: "ArsEne and Jose have responsibilities. I don't expect them to shake hands but I expect them to put the thing to bed."
