However, Bielsa says his team must learn from the setback.
He said, "The word ridiculed and humiliated are not words I would use. We took the game seriously. We were deservedly beaten as there were 20 minutes we could not manage the game. The goals they scored were deserved. We didn't create enough good chances given the time we had the ball. After there's different ways you can treat a result.
"For example, the story of Tsaroulla, their 25, it was good fortune the moment in the game and brought to life the hardship he has gone through. A homage paid to the fans, the people of Crawley, who have gone through hardship due to the pandemic. This club's most important result in 125 years. One way you can look at the game.
"Or the fact they celebrated their victory by getting drunk or brought on an actor in the second half to add to the humiliation. Of course, they're all legitimate views. I try to stay with the best one we went through.
"I don't feel we have to feel embarrassed. Nobody knows the hurt we had to go through after this defeat, but we went into this game taking it seriously. The terms used of ridiculed, humiliated, nightmare, we accept them and understand they can be viewed in this manner. Responding to your question: never do we look at a defeat in a destructive manner. We always try to look at it so we can learn from it."
