Chelsea boss Graham Potter insists they can beat Borussia Dortmund this week.
Chelsea and BVB are to meet in the first-leg of their Champions League round of 16 tie.
Potter said: "We can beat Dortmund but they are also a strong side with the capability to get a result as well. We have to understand that, go to Dortmund with humility, with respect, and try to get the result.
"It's a fantastic opportunity. We have to see it that way. Obviously, it's a tough match against a high-quality opponent. But at the same time, our team has got some good players.
"The players are confident. They are hard-working and respectful. They believe in themselves. They know it's a game of football, you have to earn the right to win. We'll go there with that approach."
