Southampton secured the biggest away win in their history as they hammered Newport County 8-0 at Rodney Parade.
Saints were dominant and led 3-0 at the break thanks to a debut goal for Armando Broja and further strikes from Nathan Tella and Kyle Walker-Peters.
A double for Mohamed Elyounoussi after the break made it 5-0 before Broja added a sixth soon afterwards.
Nathan Redmond's precise finish made it 7-0, before Elyounoussi added his third with almost the game's final kick.
The margin of victory in this EFL Cup tie was the biggest on the road in Southampton's 135-year history and matched their biggest post-war win.
