Ian Wright has singled out Nacho Monreal's mismatch with Romelu Lukaku as a decisive factor in the club's loss.
Rather than risking staying isolated up front, the Belgian frequently drifted out to the right, to leave himself one-on-one with Nacho Monreal.
Former Arsenal striker Ian Wright described the tactic as 'genius' on Roberto Martinez' part, criticising Monreal and arguing how Arsene Wenger should have switched his side around to cope with Lukaku.
"He (Martinez) put Lukaku on one of the weakest players in the Arsenal squad, he hasn't got the strength to challenge him. Sagna can at least give him a physical battle.
"I'd have like to see Wenger make a change. Take Monreal off, move Sagna over, with his athletic ability, and bring Jenkinson on on the right.
"He should have brought Oxlade-Chamberlain on earlier. He didn't do anything, it was really disappointing."
Nacho Monreal was playing in place of the injured Kieran Gibbs, and has disappointed repeatedly in recent weeks, failing to live up to his billing as a Spanish international left-back.
Monreal made just one tackle and one interception all game, but was able to complete 96 per cent of his passes and going forward, create two goalscoring opportunities.
Wright was vocal in his assessment of the entire Arsenal team.
"It was disappointing to see Arsenal play so badly at this point of the season. I would love to have seen Arsenal roll their sleeves up and make it a little bit tougher.
"The Arsenal players, you cannot expect to go to Goodison, with Everton four points behind with a game in hand and not expect a barrage. Players have to be ready. You have to quell the noise and then start playing."
