Southampton boss Ralph Hasenhttl says his team will head to Tottenham full of confidence after victory in the south coast derby during the week.
Saints thrashed Carabao Cup rivals Portsmouth 4-0 on Tuesday night, as they ended a 35-year wait for victory at Fratton Park.
"It was very interesting to watch all the videos after the game from celebrating fans in the city, on the streets dancing," he said.
"I thought we had won the cup, but it was only winning one round, against Portsmouth. But that shows how massive this win was for our fans, it was something very special, but also for us the night was something very special.
"When you see how many teams were struggling in this round, big teams, then I think it was a performance that you cannot speak too highly about.
"Wins are always good boosters, so it's important that we take the good things out of this game. It was a toxic atmosphere and it was really, really not easy to go in the game there, but we were very clinical and we saw how important it is. If you have one chance and make a goal in the right moment that can help you very, very much."
