Cesar Azpilicueta says the Premier League’s use of VAR is "difficult to understand", as the system spent yet another weekend in the headlines.
After Roberto Firmino’s armpit was adjudged fractionally offside for Liverpool against Aston Villa, Watford were awarded a highly contentious penalty against Chelsea in Saturday’s evening kick-off with Jorginho adjudged to have fouled Gerard Deulofeu, who scored the spot-kick.
The system, apparently brought in to help eliminate controversial refereeing decisions, was questioned again on Sunday as Heung-min Son was sent off for a trip on Everton’s Andre Gomes.
