After another crazy night—own goal, goalkeeping brilliance, and penalty drama—Arsenal squeezed into the Carabao Cup semi-final against Chelsea.

Kepa Arrizabalaga’s save against Maxence Lacroix sealed the deal after 15 successful penalties, adding insult to injury for the Palace defender.

Arsenal thought they’d won it late when Lacroix accidentally turned the ball into his own net while trying to defend a chaotic corner.

That's the third straight own goal by Arteta’s team at home, after two from Wolverhampton Wanderers in the Prem.

Palace's goalie, Walter Benitez, was amazing, so it felt like it would take something wild or a total fluke to beat him.

It turned out to be a fluke in the 80th minute, but Oliver Glanser’s team doesn't quit. They showed some real grit to grab an equalizer in the fifth minute of added time.

The Gunners celebrated after a nail-biting shootout came down to one miss. Arsenal advanced on their home field but had to fight hard against Oliver Glasner's team.

Marc Guehi poked the ball past Kepa after Jefferson Lerma headed down Adam Wharton’s free kick. Even though Palace dug in, they still lost.

Arsenal last won this trophy in 1993. Since then, this competition has mostly been a way to give backup players some playtime. But Arteta’s current squad is so deep that even those fringe players are looking sharp.

Noni Madueke started on the right wing instead of Bukayo Saka. He was in on goal within three minutes, after winning the ball from a Palace throw and bursting forward.

His shot went straight at Benitez, who was the only starter in Oliver Glasner’s lineup.

Benitez then denied Madueke before a brilliant save, another great save from Gabriel Jesus's header, smothering the rebound to boot. All that in the first 25!

It's been a tough week for Glasner's team, and it showed. This was their fourth game in 10 days, and they were struggling with injuries; as a result, their performance suffered. Apart from the keeper switch, they fielded their strongest possible lineup.

Lacroix’s own goal put Arsenal ahead, and his night got worse at the end.

They sat back and looked for counterattacking chances. They almost caught Arsenal’s shaky defence early when Tyrick Mitchell dashed down the left and fired a shot, but it flew over the bar.

Arsenal controlled the first half. They didn’t get Eberechi Eze involved as much as they would have liked, but he caused problems out wide.

Madueke looked sharp on the right. Gabriel Martinelli gave Jaydee Canvot a hard time. Canvot, a 19-year-old centre half by trade, looked lost trying to contain Martinelli.

Benitez made another save from Madueke before halftime, and Jurrien Timber sent a free header over the bar from 10 yards. Despite Arsenal's pressure, Palace reached halftime without letting in a goal, and Glasner made changes.

Canvot subbed off for Nathaniel Clyne, and Justin Devenny replaced Eddie Nketiah. This added some running power.

Palace looked better right away. Lerma headed wide, and Guehi miscued a shot. Wharton had more impact in midfield.

Wharton fired one past the post from 25 yards. It equalled out. Arteta responded by bringing on Leonardo Trossard for Martinelli. (Martinelli took a knock when his knees collided with Canvot’s at the end of the first half.)

Martinelli played in the second half, but he wasn't moving as freely, and the experience of Clyne gave him a harder time. Soon, Saka and Martin Odegaard joined from the bench. Eze, who scored the only goal vs. Palace in the Prem in October, and Madueke came off.

The game shifted in Arsenal’s favour again. They pinned Palace back, and Jesus headed wide after a hat trick against Palace at this stage of the Carabao Cup last season.

Palace were unlucky when they lost Chris Richards in the closing stages. As Richards was being stretchered around the edge of the pitch, Jesus fired another shot over the bar.

Glasner made even changes, with Lerma dropping into the right of the back three and Will Hughes moving into midfield.

After the first-half onslaught, Benitez was protected well until Trossard and Mikel Merino combined to give Jesus another chance.

Benitez pushed his shot over but couldn’t stop the resulting corner. Saka took it. Riccardo Calafiori headed the ball; Timber shot the blocked ball that hit Lacroix's foot and went into the net.

Arsenal thought they’d won it, but it was just the beginning. Then came Guehi’s leveller and the penalties. More pain for Lacroix. Joy for Kepa.
