West Ham manager Sam Allardyce has again criticised referee Mike Dean for his handling of Saturday 's London derby defeat by Crystal Palace . The Hammers , currently in ninth place in the Premier League , were beaten 3-1 by the Eagles at the weekend in a contentious contest . Allardyce felt that Palace striker Glenn Murray , scorer of two goals at Upton Park , before being sent off in the 69th minute , should have been dismissed by Dean in the first half for persistent fouling . Glenn Murray was sent off for Crystal Palace during the 3-1 win against West Ham on Saturday . Sam Allardyce was frustrated that Murray was not sent off earlier in the game . Allardyce said : 'The biggest problem for me was that Glenn Murray should n't have been on the field , not only because of persistent fouling but the level of his fouling . 'Mike Dean , whom I have a lot of respect for , is a very good referee , but he was too lenient with Murray by telling him 'that 's your last chance ' after the first booking . 'In that particular instance , Palace have been let off . Mike Dean has a massive responsibility on the fact that ( Murray ) was one of the main reasons why Crystal Palace won . 'And for me that is something disappointing . The fact a referee warns a player for a tackle he has just made , which normally gets a yellow card , and yet he is only warned because he has just had a yellow card . And that is frustrating . ' Murray climbed highest to open the scoring for the visitors in the first half with a header . Murray got his second and Palace 's third when he glanced a header past Adrian . Palace captain Mile Jedinak was caught on Sky Sports TV cameras apparently elbowing Diafra Sakho as they both challenged for the ball in the closing stages . Though the incident was not seen at the time by the match officials , the Football Association have since charged the player with violent conduct – and Palace have until Tuesday evening to appeal against that decision . Allardyce has welcomed any retrospective punishment , saying that the Australian midfielder deserves a ban for acting in a dangerous manner against the Senegal striker . He added : 'Jedinak was clearly in a position where Mike Dean could n't see it . I think about how dangerous it was . It was a very dangerous thing he did . He could have seriously injured Sakho . And he will have to take the punishment – because I think he deserves it . ' Mile Jedinak has been charged by the FA with violent conduct after catching Diafra Sakho with his elbow . The incident went unpunished during the game but Jedinak was retrospectively charged . Elsewhere , in his pre-match press conference , ahead of the visit of Chelsea to East London tomorrow night , Allardyce spoke about the chats he enjoyed with Dave Mackay , the former Tottenham , Derby , Hearts and Scotland enforcer , who died aged 80 . Allardyce said : ' I knew Dave . He lived in around Nottingham , when I was at Notts County for three years ( 1997-1999 ) . I spent many a good night with him talking away about his time in football , about management . 'It 's a sad day . He was a terrific guy not just a terrific a footballer . In life , you take a lot of things from a lot of people . 'If you want to get better , you do n't just read a book or do a Masters ' degree at university ; you learn a lot from listening to the experiences of people who have been great in their own careers . '
