Chelsea boss Frank Lampard insists their Champions League hopes aren't over after a 2-0 defeat at Real Madrid on Wednesday night.
Real won the first-leg on the quarterfinal thanks to goals from Karim Benzema and Marco Asensio. Ben Chilwell also saw red for the visitors.
Lampard later said: "I'm proud of the 10 men. The disappointing thing is we give away a set-piece and switch off. I don't think they carved us open at 10 men. That was due to spirit. We had our chances - Joao Felix, Raheem Sterling, Mason Mount.
"Some good things but the result is the reality. Special things can happen at Stamford Bridge. We have to believe.
"There is a lot there for us, as good a team as they are. There's a bit of a lack of belief. The players don't know how good they are.
"There was some good in there. Next week will be a big fight."
On an injury to Kalidou Koulibaly, he added: "People come in, Marc Cucurella comes in and does his job. A big deal is losing a player like Ben Chilwell.
"There are some details and mindset stuff, we have to be more positive. If we do that... I've been involved in those nights at Stamford Bridge. We keep going."
