Spurs lost 3-0 after extra-time in Croatia on one of their worst nights in recent history.
Mourinho turned on his players after a defeat leaves the Tottenham manager facing questions over his future.
“If I forget the last 10 minutes of extra-time where we did something to get a different result and go through, in the 90 minutes and in the first half of extra-time there was one team that decided to leave everything on the pitch,” said Mourinho.
“They left everything there. They left sweat, energy, they blood. In the end of the game they left even tears of happiness. Very humble, very committed. I have to praise them. On the other side, my team did not look like they were playing an important match.
“And if for any one of them it is not an important match, for me it is. For the respect I have for my own career and my own job. Every match is an important match for me. I believe that for every Tottenham fan at home every match matters and another attitude is needed.”
Mourinho continued: “To say that I feel sad is not enough because what I feel goes much further than sadness. I feel sorry that one team that is not my team won the game based on attitude, based on compromise.
“So I feel more than sad. Football is not just about players who think they have more quality than others. The basics of football go beyond that. The basic of football is the attitude. And they beat us on that.
“Before the game I told the players the risk of a bad attitude. I told the players at half-time, even at 0-0, of the risk of playing the way we were playing. And it happened. Because I believe the players only realised that the game was in risk when they scored the second goal and it went to extra-time.”
Tottenham legend Glenn Hoddle described the defeat as “disastrous” for Spurs.
Mourinho responded: “Mr Hoddle is a legend at the club and every word that he says are to be very respected. But I do not need Mr Hoddle’s words to feet myself hurt.
“I totally respect [him]. Everything that somebody connected or not connected with the club says about us tonight, I think we have to accept.
“The thing will be if some accept in a positive way in the sense of feeling hurt and ashamed with the critics. Another story is if you do not feel it if you do not care. That is a much deeper problem. I feel deeply hurt with what happened with my team.
“On behalf of my team, in spite of some of them who do not share my feelings and my emotions, I can only apologise to the Tottenham supporters. And I hope the players feel the same way as I feel.”
