With just over ten minutes to play between Cardiff and Liverpool on Sunday, referee Martin Atkinson awarded a penalty after he deemed that Sean Morrison had fouled Mohamed Salah in the box.
James Milner converted the penalty, easing Liverpool to a crucial 2-0 win in their challenge for the title.
Speaking after the game, Cardiff manager Neil Warnock said that he thought it was a "soft penalty". He also likened the actions of Salah to Olympic diver Tom Daley.
"We gave him [Salah] an opportunity, didn't we?" said Warnock.
He [Morrison] had his arms around Salah, but I think the end of it was a 9.9 Tom Daley job. I don't think he could have got much higher off the diving board.
I'm sure you'll be saying that Warnock is a moaning so and so again.
The win moved Liverpool to the top of the Premier League, two points ahead of Manchester City. Though, they have played a game more.
With three games to play this season, Cardiff are still inside the relegation places in 18th. They are three points behind Brighton who have also played one game fewer than Cardiff.
"I think just after half-time, the tug on Morrison's shirt, which should have been spotted [was a penalty]," continued Warnock.
"It stopped him having a clear header at goal. Nothing much said about that, but we haven't had any of those.
"He's been absolutely pulled from post to post has Morrison and we haven't had one penalty. We're not going to start getting them now.
"That was disappointing but they said the sun might have got in the linesman's eyes for that one.
"We're still fighting. I think Jurgen should do a job swap with me for a week. They're doing that well, he should let me have his team for a week, he should come and have mine."
