Mourinho was impressed by the home support during the 1-0 reverse.
"We started better than we finished the game. I waved to the Betis fans because they are fantastic and after a difficult week and a week in which there has been conflict with some of their players, they were able to be fans and help their team win," said Mourinho.
"That pleased me because they behaved correctly and supported their team. I congratulated the Betis players because it's not their fault that the Benzema goal was ruled out or that the penalty wasn't given in the last minutes of the match."
