After 15 successful spot kicks, Kepa Arrizabalaga was the quarter final hero for Arsenal, denying Maxence Lacroix to book his side a spot in the Carabao Cup semi-final.
The Crystal Palace man had given the Gunners the lead having poked the ball into his own net with 10 minutes left to play of normal time, before Marc Guehi struck late at the Emirates to force a penalty shootout.
The Frenchman then missed the decisive penalty to compound his misery and send Arsenal through to face London rivals Chelsea in a two-legged clash, with a cup final at Wembley Stadium on the line against either Manchester City or Newcastle United.
Here are four things we learnt from Arsenal's quarter final triumph.
The Arsenal goalkeeper was the hero on the night, producing the all important knockout blow to Crystal Palace's cup ambitions with a fine save to keep out Lacroix's spot kick.
It was a big moment for the Spaniard, having had very little action all game, only to be beaten through his legs by Guehi's instinctive late finish. The former Chelsea man then saw seven consecutive penalties fly past him in the shootout, before finally guessing the right way and fabricating the winning moment.
The Gunners' back up shot stopper has had a torrid time in recent Carabao Cap campaigns with his former club, having reached and lost two finals with the Blues. 2019 saw Kepa refuse to be substituted late on against Manchester City, and three years later in 2022, he blasted the pivotal final penalty over the bar against Liverpool.
A Game of Two Halves
Arsenal controlled proceedings in the first 45 minutes, playing free flowing football and creating countless opportunities for the likes of Noni Madueke and Gabriel Jesus, only to be denied by an inspired Walter Benitez in the Palace goal.
In contrast, the second half saw the visitors emerge as a new team, taking better care of the ball when in possession and turning the game into a more scrappy and physical encounter, disrupting Mikel Arteta's side.
A goal manufactured from a corner each summed up the rhythm of the second period, with the Gunners finally breaking down a stubborn Palace defence with an own goal, their third in a row in front of home fans, only to be pegged back late on.
Gabriel Martinelli's Top Performance Dampened by Injury
Gabriel Martinelli made the first half his own by tormenting the makeshift Eagles wingback Jaydee Canvot, to the extent where the latter was substituted by Oliver Glasner at halftime. Arsenal's Brazilian winger was direct with his running, underlining his unpredictable ability to beat his man by either cutting inside or driving round the back to the byline.
In a rare instance where Arsenal focussed their attacking play down the left wing, perhaps due to Bukayo Saka's omission from the starting 11, Martinelli was then halted in his tracks by a knee on knee impact injury with Canvot.
Having limped off the pitch with a few seconds left to play in the first half, Arsenal's number 11 re-emerged for the beginning of the second 45 minutes, only to be withdrawn at the hour mark, clearly still struggling.
Willian Saliba's Man of the Match Performance
Martinelli was well on his way to earning the award but, following his early departure, William Saliba snapped up the honour. The centre half was assured at the back, dealing with the physical task of Jean-Philippe Mateta and timing his tackles to perfection.
He also was progressive with his passing, stepping forward with the ball at his feet before finding a route through the Palace midfield with positive passes into the Arsenal forwards.
To top off his performance, the Frenchman coolly tucked his pressure penalty away in the shootout, sending Benitez the wrong way and finding the bottom left corner.
