Kepa Arrizabalaga was the hero as he saved the decisive penalty from Maxence Lacroix to help Arsenal beat Crystal Palace in a shootout and progress to the semi-finals of the Carabao Cup in a game packed with late drama.
The Gunners thought they had won the match when the unfortunate Lacroix scored an own goal in the 80th minute, bundling the ball into his own net when trying to clear after an Arsenal corner.
However, Palace got a dramatic leveller in the fifth minute of stoppage time when Adam Wharton floated in a free-kick and Marc Guehi was the quickest to react to Jefferson Lerma's knockdown to score from close range.
Declan Rice then had a chance to win the match for Arsenal with the last kick of the game, but he could not score past the excellent Walter Benitez.
The stand-in Palace goalkeeper had been their best player throughout the match, making two excellent saves from Gabriel Jesus to keep the scores level until the latter stages.
The Palace centre-back's night got worse when he stepped up with the score at 8-7 in a high-quality penalty shootout and Arrizabalaga got down well to his right to push the ball away and give Arsenal the win.
The Gunners move into the last four of the competition and will face London rivals Chelsea over two legs for a place in the final.
