Sunderland boss David Moyes is hoping his side can use the confidence from their emphatic away win at Crystal Palace last weekend when they meet Southampton.
Four first-half goals at Selhurst Park without reply saw them move level on points with their opponents as they look to move away from the bottom of the Premier League table.
And Moyes says they must maintain that sort of level of performance if they are to pull away from danger.
He said: “We had a great result last week and the players showed exactly what they can do.
“It was a very all round team performance both in terms of scoring goals and probably more importantly keeping clean sheets and cutting out mistakes.
“If we play at that level we’ll give ourselves every chance of moving off the bottom of the league.
“We’re in a good mood but we also know that we’ve got a long way to go and a lot more to do.”
Saints head to the Stadium of Light on the back of three defeats, and are in search of their first away points on the road in 2017.
“I think Southampton have got a good team. I think the cup might have been a bit of a distraction for them and you’ve got to remember they’ve had European football as well,” Moyes added.
“I think they’ve done a really good job as a club generally. They’ve had to sell a lot of players and change managers for different reasons.
“I think they’ve got a really good side but we have to forget about that in this game and make sure we go out and prove we can win the game.”
