Arsenal moved one step closer to securing their first major trophy in six years after they beat Chelsea to reach the Carabao Cup final, and what happened after full-time at the Emirates Stadium spoke volumes.
Holding a slender one-goal advantage from the first leg, the Gunners were pushed all the way by their London rivals and in the end, it took a 97th-minute winner from super-sub Kai Havertz to settle the tie and spark wild celebrations.
Indeed, when the decisive finish went in, the home support erupted, and the message from the stands only grew louder once the final whistle blew.
What did Arsenal fans sing after beating Chelsea?
Havertz was introduced in the 69th minute in place of Viktor Gyokeres and made an immediate imapact.
In the dying moments of injury time, the German calmly rounded Blues goalkeeper Robert Sanchez before rolling the ball into an empty net, sending the Gunners through in unforgettable fashion.
Soon after, the Emirates Stadium sound system cranked up Shakira's ‘Waka, Waka' song, the tune long associated with Havertz's catchy chant.
Fans around the ground sang “£60 million down the drain, Kai Havertz scores again!” as the players celebrated with them on the pitch, making it clear who they believed changed the second leg.
FGG says: Mikel Arteta now faces big Arsenal striker decision
For Mikel Arteta, the scenes would have been jubilant, but perhaps an uncomfortable decision is soon on the horizon.
Gyokeres endured a difficult evening, managing only one shot and ten touches across his 69 minutes, per Sofascore, subsequently offering little influence to the game.
The £55 million summer signing has shown flashes of promise this season, but consistency has been an issue, and a debate continues to rumble on over his suitability for the way Arsenal play.
Havertz, by contrast, once again delivered when it mattered most – he is proven in Arteta's system and often trusted in the big moments when fit.
With the Gunners sitting six points clear at the top of the Premier League table and entering a hectic February schedule, the message from the stands couldn't be clearer.
On nights like this, where everything is on the line, the Emirates seems convinced they know who should be leading the line – but will Arteta agree?
