Despite the use of Video Assistant Referee system (VAR), referee Graham Scott failed to award Chelsea a penalty in the game against Norwich after Willian was brought down in the box by Norwich defender Timm Klose.
Willian was instead booked for diving when replays showed it was a clear penalty.
Former Premier League footballers Alan Shearer, Phil Neville, Dion Dublin and Gianfranco Zola all agreed it had to be a penalty.
“You saw VAR work perfectly last night (at Leicester v Fleetwood),” Shearer said on BBC One.
“You’re seeing why I was very doubtful about it now.
“It’s a shambles because you’ve got one, two, three, four ex-footballers in here, Jermaine Jenas, five, and we all think that is a clear and obvious penalty and he even books him for diving!
“Who on earth is looking at that screen at Stockley Park (Premier League studios HQ) and doesn’t think that’s a penalty? Now, that’s why it’s all wrong because it’s somebody else’s opinion and that’s why it’s a shambles.”
Phil Neville added: “That is a penalty. There is a clip. It has got to be a pen.”
Dion Dublin added: “It’s a shocking decision, honestly. I don’t know how they’ve got it wrong. They’re watching the same replays as us and it’s clear and obvious that’s a penalty.”
Gianfranco Zola said: “He had no reason to go down there. He was going to shoot and probably score.”
