The West Ham manager does not even think the midfielder's challenge was worthy of a booking, let alone a dismissal.
A clearly-incensed West Ham United manager Slaven Bilic has told reporters that there is no way that Cheikhou Kouyate deserved to be shown a red card against Crystal Palace on Saturday and said he is "fed up" with having to appeal contentious decisions, as quoted by the Sun.
The Hammers were 2-1 up against Palace at half-time and on course for a victory which would have kept them within a point of the top four and with a six-point buffer between them in fifth and Southampton in seventh.
However, Kouyate was shown a straight red card for a clumsy challenge made on Palace striker Dwight Gayle, who equalised eight minutes later as the one-man advantage paid dividend.
That was the latest in a line of recent contentious decisions to go against West Ham, with a penalty being awarded to Chelsea for a foul which appeared to take place outside of the box a fortnight ago, and Dimitri Payet being penalised for diving when it looked like he had actually been fouled in the match before that.
Bilic was clearly incensed and exasperated with the latest decision, which he believes was not even worthy of a yellow card, and though he chose his words carefully, he admitted he is fed up with having to appeal decisions.
The Croatian boss told reporters, as quoted by the Sun: "We have every right to be disappointed with it. It was never a red card. Not even a yellow. In English football, maybe not even a foul. Ok it was a foul. But it was just a 50-50 ball.
"I don’t know why I cannot make any more comment about something which is affecting my job. But make no mistake, we are disappointed.
"This is four times in the last four games this has happened. I’m fed up with appealing."
It's no wonder that Bilic is frustrated, as that decision, and the equaliser which shortly followed it, could prove costly in the Hammers' chase for a first-ever qualification for the Champions League.
With just seven games remaining, Bilic's side are now three points behind Manchester City in fourth spot with Arsenal, Leicester City, and Manchester United amongst the teams still to play.
Given the relative difficult of their fixture list, a home tie with a desperately out-of-form Palace may well prove to be a game that they simply had to win.
