Chelsea boss Rafa Benitez is backing his team to overcome the odds against Swansea on Wednesday to book their place in the final of the Capital One Cup.
Benitez's side must overcome a two-goal deficit in the second leg at the Liberty Stadium on Wednesday if they are to reach Wembley.
"We have confidence that we can do it. It's not easy, but we've done it before in other stadiums and we can do it," said Benitez.
"We have to score and win. For them, it depends: 2-0 up, they could wait and play counter-attack. They could try to pass the ball and attack, but I think they will wait for us.
"We have to go there and try to win. Not just 1-0 - we have to do a bit better than that. But we can do it. We have enough quality."
The Capital One Cup is a big chance for Chelsea to secure some silverware this season, especially after Benitez recently made it clear he believed they were out of the Premier League title race.
Defender Gary Cahill contradicted his manager, saying Sunday's 2-1 win over Arsenal, which moved the Blues to 11 points behind leaders Manchester United, has kept them in the hunt.
"He (Cahill) has confidence in the team," Benitez added. "He knows we can win. If we want to win three trophies, we'll have to win this game."
