There are still 2 weeks left and anything can happen in a short time as you said. Injured players are always a bad choice for a team and this is not only true for Madrid but the opposing team can be worse when they lose injured players.
From the hopes of Madrid fans when facing Liverpool, only a draw is the best result if they can't beat Liverpool. It may seem bad for one of Madrid big teams to end in a draw. But that result would be better than losing.
Most likely if Liverpool loses important players injured, maybe taking a gamble on a draw is the best choice.
I see the possibility of Real Madrid winning with Liverpool is very low. Even after injuries to their team players, their team started to decline. Given their team's status and recent form, a draw against Liverpool would be the best gift for Real fans. If they can beat Liverpool and take 3 points, it will be overwhelming for the Real Madrid team and their fans.
Real Madrid's recent performances speak against them. In such a situation no gambler would agree to bet on their behalf. We are always optimistic that Real Madrid will return to their old form very soon. Realizing this hope with an injury-prone squad is almost impossible for Real. To survive in the Champions League, they must come up with a new plan.
We might all be thinking that Real Madrid will suffer a disgraceful defeat from Liverpool but when the time comes, Real Madrid will turn around and fight Liverpool to standstill. They have all it takes to achieve that and we should not forget that Real Madrid have experienced players who have tasted different trophies, so they know how to navigate a difficult time because they have been there before and came out stronger. This is just me thinking outside the box. I know Real Madrid have a major problem but their problem can be fixed through a many change to the team formation.
