Perhaps the most unsettling of lenses through which the defeat has been seen regards Arsene Wenger - whose generally unchallenged position at the helm has been heavily questioned.
The Frenchman’s opposite number at Stamford Bridge has made no bones about his lack of inspiration from a fellow tactician verging on nine years without a trophy.
In Arsenal circles, the issue of whether to continue Wenger’s recently barren tenure at the Emirates remains divisive, though high-profile detractors haven not been in short supply after the weekend’s events.
Reports have suggested that the longtime boss has retained the confidence of the club hierarchy and will renew his expiring contract, even given the summer’s close proximity and a title charge that has been dashed on jagged rocks at this point.
Ex-Gunner Robson has taken a particularly damning route in judgement of Wenger - queuing up an alternate universe in which Mourinho is the man on the Arsenal bench.
“If Jose Mourinho was in charge of the Arsenal squad, they would be six, seven, eight points better off than they are now because he is a better coach,” Robson told talkSPORT.
“He understands what it takes and getting the balance right between the attacking side of the game and defensive side of the game.
“He knows that he wants his players to do certain jobs in the team.”
And Robson does not see the situation - silverware-wise that is - improving for his former employers in the short term.
That is, unless Wenger is replaced - with the Frenchman’s lack of answers for heavy defeats to the Premier League’s top sides forming his case against the manager.
“I don’t think they will win the Premier League in the near future,” he continued. “I think they need a change of manager.
“Arsene Wenger said we are not quite sure how it [the Chelsea loss], but it happened at Liverpool, it happened against Manchester City, it happened a little bit against Southampton.
“How does he not know what happened? Arsenal don’t earn the right to play.
“Unless teams drop off and allow Arsenal to play, they can’t cope with the physicality.”
