Sunderland captain John O'Shea is desperate to transfer his side's form in the Capital One Cup to the Premier League after a famous victory over Manchester United at the Stadium of Light.
The Black Cats will take a 2-1 advantage to Old Trafford in the second leg of their League Cup semi-final against David Moyes' men after a spirited performance on Tuesday.
Yet the Wearsiders cannot afford to rest on their laurels as they are at the bottom of the standings in the Premier League, four points adrift of 17th-placed Crystal Palace.
That is not lost on O'Shea, who told Sky Sports 1: "Whatever it is we need to bring it into the league very quickly. The players know we have plenty of quality, it's just making sure we use it at the right times.
"We seem to be doing it quite well against the best teams so we have to make sure we do that in the league as quickly as possible because we know we're good enough.
"But we've seen good teams get relegated before so we have to counter that quickly and get the points on board, but a win like today will give us a massive boost."
The performance of debutant Marcos Alonso will have given Sunderland fans plenty of reason for optimism in the coming weeks, with the left-back putting in an accomplished performance.
"I've only known him for a few days but he's been very bubbly in the dressing room and you saw the quality he has tonight playing against Valencia, he did outstanding," added O'Shea.
"He probably had a few cramps in his legs but it's well deserved."
Alonso was euphoric after playing in his part in handing United their third successive defeat for the first time since 2001.
But, like O'Shea, the former Bolton man was quick to turn his attention to Saturday's crucial clash at relegation rivals Fulham.
"I'm really happy because the team needed this win," said the Spaniard.
"The last games they had really good performances but the score wasn't the one they wanted. We got it today and now we don't have time to think about it.
"We just have to focus on the game against Fulham on Saturday and keep going."
