Manager Jose Mourinho says it is a "disgrace" how Chelsea were knocked out of the FA Cup against Bradford.
Only twenty four hours before the game, the Portuguese said that his players will show Bradford the respect they deserve as the defeat ends Chelsea's hopes of the quadruple.
But the Blues threw away a two-goal cushion, conceding three goals in the last 15 minutes of the game, in what Mourinho called an embarrassment at the end of the game.
"I don't feel so upset with myself because I did my work properly," Mourinho said.
"I thought I prepared my players. At half-time I told them exactly what could happen. Obviously I am also responsible for that, but the reality is that this happens a lot of times in this country.
"Never to me. It is the first time it happens with me in English football.
"I can feel really happy for them. I was in that dressing room but at the same time I use the same word I used yesterday. It is a disgrace we were knocked out.
"What happened is football and football is beautiful.
"I think this is the beauty of football where a much better team can lose, which is difficult to happen in another sport and more possible to happen here in this country and this sport.
"The small team mentality is special. My respect goes to that and to them, they did a fantastic history for them and their club.
"I repeat a word I used before this match - It's a disgrace for a big team to lose to a small team from a lower team.
"We must feel ashamed, me and the players must feel ashamed. Frustration is not the right word, embarrassed would be more appropriate."
