Real Madrid is indeed a defense line with many injuries, this is a weak composition, plus Mbappe is not so dominant, only Vini and Bellingham can be relied on on the front lines.
Liverpool does not need to be in doubt, I think they play at home will play more dominant because of the current performance, while Real Madrid will still have difficulty against an equal team they will no longer be strong in the fragile back line defense.
...all they need is to get the ball to those front guys and they will be fine if the front guys does not mess things up,they will still have trouble with their defence though not making it obvious depends on them .
