The failure to send the Argentine midfielder off in the Blues' derby win over London rivals Tottenham left the Stamford Bridge boss incensed
Frank Lampard slammed VAR as "not good enough" after Giovani Lo Celso avoided a red card for an awful challenge on Cesar Azpilicueta in Chelsea's win over Tottenham.
The Blues ran out 2-1 winners at Stamford Bridge, with goals from Olivier Giroud and Marcos Alonso before Antonio Rudiger put through his own net as Spurs threatened a scarcely deserved fightback.
But prior to Tottenham's goal, the visitors might have been reduced to 10 men as Lo Celso might have been dismissed after planting his studs into Azpilicueta's shin.
