Real Madrid goalkeeper Thibaut Courtois believes the 4-0 defeat to Barcelona at the Estadio Santiago Bernabeu was nothing more than a fluke.

The Belgian goalkeeper feels that Real Madrid's results have drastically improved since then which indicates it was merely a bad day at the office for Los Blancos against their rivals.

"It was a very bad night, but we recovered quickly, because you shouldn't have to think too much about defeats," he told El Capitan.

"I'm disappointed, of course, but I think it was clear that there is a before and after that defeat.

"If you look at our results and our performance it was a fluke."

Courtois hailed his side for the comeback win over Paris Saint-Germain.

"It was a wonderful dream," he said.

"After the first leg, few fans believed we could qualify, but we did it.

"It was one of those many nights when I feel lucky to play for Madrid."
