Kompany said he was unsure whether Neuer would be available in the coming days, but backed his side's quality in all positions.

"It's a pity for us, but I've spoken before about our squad. When it's Urbig, then it's Urbig, and we won't think about it for a second," he told DAZN.

Self-inflicted errors

Leverkusen boss Alonso lamented his side's self-inflicted errors, saying it needed a "big miracle" to reach the quarterfinals.

In the 2005 Champions League final with Liverpool, Alonso helped the Reds come from 3-0 down against AC Milan, scoring the equalizing goal, before his side eventually won on penalties.

The match became known as the "Miracle of Istanbul", and Alonso suggested his side will need similar heroics if it is to have any chance of progressing to the final eight.

"After this game, we'll need a bit of time, and, after we recover, in football we've seen big miracles quite often and we almost need one.

"It's football, it's not my first time, and there's another game at home."

Coming into the tie as slight favorites, and having not lost to Bayern in six games since taking over as coach in October 2022, Alonso's men were outclassed and produced several individual errors.

Speaking with DAZN, Alonso was asked why his team had failed to reproduce its recent strong performances against the German giant.

"Why? It was clear. I think we did it to ourselves. We know the details are important in the Champions League, and the second goal, the red card and the penalty, we gave Bayern everything they needed to win."

Alonso, who had called for cooler heads and "emotional control" before the match, suggested his side needed to navigate the game better.

"We need to play maturely, to control the game better, and today we gave all the chances to Bayern to win 3-0.

"The mistakes, the details are important. It's a bitter evening, of course."
