Antonio Rudiger claims Chelsea dominated Real Madrid in the Champions League quarter-final second leg on Wednesday.
Having lost 3-1 in the first leg, the Blues seemed destined to reach the semi-finals when Timo Werner made it 3-0 at the Bernabeu.
But goals from Rodrgyo and Karim Benzema saw Real claim a 5-4 aggregate win.
"The positive is we didn't give up," Rudiger told the club's website.
"Not many teams can come here and dominate them as we did. But the big "but" is, over the two legs we made these type of mistakes. Against Real Madrid you get punished.
"We were close. I think we dominated them and we outplayed them, we outran them, but at the end of the day it's little details that we missed.
"We scored three goals, I think not many can come here and do that. For me we outplayed them, we outran them and we did a fantastic match, but if you look at both games we need to win these."
