RB Leipzig coach Julian Nagelsmann rued their defensive errors in defeat to Liverpool.
Liverpool have taken control of their round of 16 Champions League tie with a 2-0 first-leg win in Budapest.
Nagelsmann lamented, "We made two goal mistakes, two serious mistakes.
"Mistakes in football happen otherwise there would never be goals. We cannot cry too much, we could certainly have done better.
"We made a lot of mistakes but I saw the commitment of my boys. Now there is the return match, we will try to make less mistakes and look for this result."
