Liverpool boss Brendan Rodgers is fed-up with the treatment of Luis Suarez after his frog splash on Sunday.
Stoke City defender Robert Huth escaped punishment despite appearing to stamp on Suarez after the Football Association confirmed the incident was seen by officials at the time and therefore no further action can be taken.
That has left Rodgers outraged.
"As manager of this football club I find it incredible that in nearly all the coverage about Luis Suarez this weekend, very little focus has been placed on the fact that he was actually the victim of a stamping incident within the first five minutes of the game," he told liverpoolfc.com.
"At this moment there seems to be one set of rules for Luis and another set for everyone else.
"Diving and simulation is obviously a wider issue in football and one that we all agree has to be eradicated from our game but there were other incidents this weekend that didn't seem to generate the same coverage.
"No-one should be distracted by the real issue here, both at Anfield and at another game played on Sunday, when Luis and another player were hurt in off-the-ball incidents that went unpunished but were caught on TV cameras.
"I believe some people need to develop a sense of perspective and I also believe in this moment the vilification of Luis is both wrong and unfair.
"I will continue to protect the values, spirit and people of this great club and game while searching for a consistent level of results in order to make progress on the field."
