On Monday, Nagelsmann said Villarreal had made a mistake by using triumphing the primary leg by way of a slim 1-0 margin "which allowed us to live on".
"In the primary leg we made the mistake of now not completing them off. All the comments about that served as motivation," said Moreno, whose cross set up Chukwueze's tie-prevailing strike.
"What this group has finished is exceptional."
Robert Lewandowski had put Bayern ahead at the night time to level the tie.
Unai Emery's Villarreal had already knocked out Juventus in the closing sixteen following a lovely three-zero win in Turin.

"We are transferring forward step by step, we had a very difficult quarter-final."
