Late goals by Cezar Apzilicueta and Ruben Loftus-Cheek saw Chelsea steal victory after an abject display.
However, Chelsea's last-gasp turnaround means that they keep up with the side's above them and put further pressure on Tottenham Hotspur who play Liverpool this afternoon.
The manner of the defeat visibly annoyed manager Warnock, who exchanged words with opposite number Sarri before heading out onto the pitch at full-time to stare down referee Craig Pawson and his assistants. "To get let down by the officials. roll on VAR", Warnock told Sky Sports.
Cardiff manager Neil Warnock was fuming with the officials following defeat by Chelsea
"It's the best league in the world but the worst officials", he said.
"I would like to see him at the top in the last two months", he said.
"It's hard because I am really flat".
The away supporters had audibly grown exhausted of the Blues' lethargic play and a complete lack of elite-level cutting edge in attack but, in truth, Sunday's game was not a far cry from the problems which have permeated the second half of Chelsea's season.
"If I was a Burnley or a Brighton fan [two of Cardiff's relegation rivals], they will be absolutely loving it today". Kante, Giroud, Hazard, played three matches in seven days and now we are not in October, they are more exhausted.
"It hurts. The referee had a decent game but we didn't get the major decisions".
"Say you did watch it, give the lad a little bit of a gee up". The race for the top four this season is one of the most intense in recent history with Tottenham Hotspur, Manchester United, Arsenal and the Blues all chasing a Champions League qualification spot for next season.
Callum Hudson-Odoi will soon be starting up to 80 per cent of Chelsea's matches, according to head coach Maurizio Sarri.
Let us know in the comments. 'If my players feel like they look in the dressing room, that's the end of our season. I am getting used to this and for me, it's not a big problem.
I can imagine the people above Sarri just shaking their head and thinking 'why are you saying such a stupid thing in the press conference?'
Sarri later opted to bring on Olivier Giroud and Ruben Loftus-Cheek, who eventually scored the victor, but fans were not happy at his tactics throughout.
It was the defender's first goal for nearly a year, but it could prove so precious to both Chelsea and Sarri's future.
