Giovani Lo Celso escaped a red card for a horror tackle on Cesar Azpilicueta during Saturday’s derby clash.
Despite a lengthy VAR check, which showed Lo Celso’s studs connecting with Azpilicueta’s right foot, the Argentina international was not even booked.
It was a similar tackle to the one which saw Arsenal skipper Pierre-Emerick Aubameyang sent off for a lunge on Crystal Palace’s Max Meyer last month.
Stockley Park, where the video assistant referee operates, have since admitted Lo Celso should have been sent off for the tackle.
Lo Celso’s late tackle could have come from frustration with Tottenham conceding goals to Olivier Giroud and Marcos Alonso strikes either side of half-time.
talkSPORT pundit Ray Parlour could not believe Lo Celso remained on the pitch.
He said: “How’s that not a red card at Chelsea?”
Meanwhile, Michael Owen echoed Parlour’s thoughts.
He added: “Two potential red card incidents involving Lo Celso. Can’t believe he’s still on the pitch. Again, the technology does its job but the VAR referee makes a very poor decision.”
