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.
