By rescinding the red card, the FA have confirmed that they believe that the referee's interpretation of events was incorrect. That stands for the actions by both players in question.
The FA do have the power, but they're choosing not to exercise it.
The standard of referees has declined in the last five years, it's impossible to put a coherent argument forward to contradict that.
I accept that the players' actions don't help, but the referees haven't adapted to the modern climate, which in the professional era is unforgivable.
Have referees ever studied body movements or simulation when compared to impact? Who knows, if you studied enough, trends may become apparent in body part movements at impact, flight or landing. Whilst diving is a cancer on our game, the referees are the ones buying the fags as opposed to giving it chemo. There's zero effort going in to seriously stopping it.
By rescinding the red card the FA have said that Sako was not guilty of violent conduct. The reaction of the other player does not come into it. Had Sako pushed him, then the red card would have stood irrespective of the Watford players disgraceful reaction.
Please tell me what powers the FA have to take action against the Watford player. The referee confirmed he saw the incident, which I have my doubts about, but having dealt with the incident, the FA do not have the power to take retrospective action. If they tried to, an appeal would be made to FIFA, which would be won. The FA cannot act contrary to the rules of FIFA, of which the English FA is affiliated to.
Please put forward a coherent argument as to why standards have declined.
What do you mean by the modern climate? If you mean an era of blatant cheating by players, then yes referees have not adapted to that. But how can they? The clubs are the ones who should be stopping their players from cheating, but with the amount of money at stake, this will not happen.
Referee seminars now include a section on simulation, but the simple fact is that in the pressure of the game, referees have to make instant decisions, and do on occasions get it wrong. The game today is very quick, and these incidents can happen in a flash, and the referee cannot stop the game to have a look at a video replay, he must make his decision there and then. You say there is zero effort going into stopping diving, but there is, but it is so difficult, and until the clubs come on board to stop this blatant cheating, then it is difficult to see things changing in the short term.
