Southampton dumped FA Cup holders Arsenal out of the competition on Saturday, winning 1-0 courtesy of a Gabriel own goal to set up a fifth-round meeting with Wolves.
The much-changed Gunners, who have won the competition a record 14 times, fell behind midway through the first half and could not find a way back.
Ralph Hasenhuttl fielded a strong side at St Mary’s, with Danny Ings returning after a hamstring injury and a positive coronavirus test alongside former Arsenal forward Theo Walcott.
Southampton, who had never previously beaten Arsenal in the FA Cup, were the brighter team in the first half in the winter sunshine on England’s south coast.
James Ward-Prowse rattled the crossbar from a swerving corner and Che Adams forced a fine save from Arsenal goalkeeper Bernd Leno.
