Improper conduct charges for Pardew and Wenger
Arsene Wenger and Alan Pardew could both face the possibility of a touchline ban after being charged with 'improper conduct' by the Football Association in the wake of their bust-up at Upton Park.
The two bosses had to be separated following Marlon Harewood's late winner for the home side in the Barclays Premiership match on Sunday, following celebrations by the West Ham coach in the technical area.
Frenchman Wenger refused to shake his rival's hand at the end of the match, and left without speaking to the press.
Pardew issued his apology immediately, with the League Managers' Association set to attempt mediation.
The FA, meanwhile, have today decided there is a case to answer for each man.
A statement on the FA website read: 'West Ham United manager Alan Pardew and Arsenal manager Arsene Wenger have both been charged with improper conduct.
'The charges relate to their alleged aggressive and confrontational behaviour towards the end of the match at Upton Park on Sunday, November 5.
'They have until November 23 to respond.'
Each manager has the right to request a personal hearing, and the footballing authorities have the power to impose a fine or even a touchline ban should the charge be proven.
Wenger has so far remained silent on the incident.
The Arsenal manager did not speak to the media directly after Sunday's game, and with no press conference scheduled ahead of the Carling Cup clash with Everton, any comment is unlikely to be forthcoming until post-match at Goodison Park tonight.
West Ham, however, have vowed to 'defended vigorously' the charge against their manager.
The east London club's managing director Paul Aldridge said in a statement on their official website: 'West Ham United are astonished by this charge.
'We believe Alan Pardew did no more than celebrate in a passionate manner following a crucial goal in a London derby.
'Alan Pardew has the full backing of the board with regards to this charge, which will be defended vigorously.'
