Sunderland's Gus Poyet hopes his side's Capital One Cup win over Chelsea can inspire his team in the Premier League.
Ki Sung-Yueng's extra-time winner sent bottom of the table Sunderland through to the semi-finals, at the expense of third-placed Chelsea.
"I want to transform the mentality of this group of players, I want them to become winners," said boss Poyet.
"When you can prove you can beat the best in the country, you should do the same against the other teams."
Since Poyet's arrival on 5 October, Sunderland have won just four of 11 games and remain five points from safety in the Premier League.
Yet the Uruguayan is determined to stick to his style of possession-based football.
"It doesn't matter about our position, we just need to be ourselves, play the way that we play and keep going non-stop for 90 minutes," he told BBC Sport.
"It's not easy. To maintain the level and the belief for 90 minutes is very difficult. I think we are getting close to making that happen.
"It doesn't matter who you play against, if it's Norwich or if it's Carlisle in the FA Cup, the more we do it, the more difficult we are going to become to play against, I am sure."
