There was no disguising the magnitude of the fixture in the build-up this week.
Arsenal sat sixth in the table with just one win from three and were thumped by Bayern Munich in Europe on Wednesday. Meanwhile, Chelsea had won their three matches under Bompastor.
That was some context behind the intensity that had been building for Arsenal manager Eidevall, who is in his fourth season in charge of the club and has not delivered a WSL title.
A London derby against rivals Chelsea was arguably the toughest test Eidevall could face, with many fans entering the Emirates Stadium on Saturday demanding a response having already expressed a desire for him to stand down from his role as manager.
So when Baltimore headed in Chelsea's second goal within 16 minutes, having been allowed to run into the six-yard box completely unmarked, frustrations bubbled over.
Leah Williamson was given a torrid afternoon by Chelsea striker Ramirez and she spent the majority of the first half complaining to officials as things didn't seem to be going her way.
But Arsenal's persistence did not falter and Foord, their standout player of the afternoon, danced past England full-back Bronze and fired the ball into the corner from a tight angle to give them a lifeline going into the half-time break.
As the second half started, the rain fell heavily, and Chelsea started to struggle in the face of Arsenal's relentless onslaught.
Russo's powerful volley gave goalkeeper Hampton something to think about in stoppage time, after she watched Blackstenius' strike smack the underside of the crossbar.
But despite their fight, the result leaves Arsenal trailing league leaders Chelsea by four points, having played just four matches, and discontent towards Eidevall is likely to intensify.
Meanwhile, defensive frailties clearly remain for Chelsea and they allowed Arsenal back into the game, but Bompastor's winning run continues.
"It was not a concern but there is always room for improvement and I clearly see where we need to improve as a team," said Bompastor.
"We need to be more consistent. We have experienced players and need to manage the tempo in the game.
"It is hard to come here to play against a really good team away from home. We suffered for sure but it’s a good thing we did not concede a goal."
