Bolton boss Sam Allardyce has hit out at the Football Association's decision to rule out taking any action against Liverpool duo Steven Gerrard and Mohamed Sissoko.
Allardyce was unhappy that Gerrard and Sissoko were not punished after alleging the pair had stamped on his players in two separate incidents during the 2-2 draw at the Reebok on Monday.
However, referee Mark Clattenburg has confirmed in his match report that he saw both Gerrard's clash with Kevin Nolan and Sissoko's tackle on El-Hadji Diouf.
Under FIFA rules, the FA cannot take retrospective action against players using video evidence if the match official witnessed the incident at the time,
The ruling has not appeased Allardyce, however, and he said: 'Our procedure has to be seriously flawed. I have to find out all the reasons why neither player has been punished.'
Gerrard has also been cleared of blame by Nolan himself, who dismissed the alleged stamping as merely an accident.
However, Allardyce refused to take that view on board, stating: 'I think Kevin has a clouded view of this because Steven Gerrard is a friend.
'Because he has defended him it does not make what Gerrard did right. For me, it was still a bad foul and the intent was there,' quotes The Sun.
The FA also confirmed there will not be any disciplinary action taken against West Ham's Nigel Reo-Coker for his bruising tackle on Chelsea's Michael Essien.
Essien was stretchered off with an ankle injury following the late tackle by the England Under-21 international midfielder at Upton Park, where Chelsea won 3-1.
However, referee Howard Webb penalised the foul with a free-kick at the time, choosing not to book Reo-Coker or send him off.
An FA spokesman confirmed: 'There will not be any disciplinary action because the referee dealt with the matter at the time by awarding a free-kick to Chelsea.'
