Real Madrid at this moment knows that every point counts in their quest to progress to the next round of the competition? A home game against Salsburg I think will be an easy one for Carlo Ancelotti's men to get all three points. The quality of players at Real Madrid can't be matched by that of Salsburg, and now that Real Madrid knows they might fail to progress to the knockout stages of the competition, you should expect nothing but their very best in that game. My prediction is that Real Madrid will win that game as well as register 2+ goals.
That would be nice to bet on if you are quite sure of that outcome. Because the probability of happening may be indeed high as they have the motivation to achieve such position. But don't bet high stakes as you can't still guarantee the results. Be conservative with the amount of your bet even if you feel you will hit it right.
Real Madrid matches against RB Salzburg and Brest; you will have some bettors risking that, to bet against Real Madrid to lose any of the matches, which the odds for that will be much if Real Madrid is to lose any of their two upcoming Champions League matches.
The new match format is not favorable to big teams. Betting on big teams to win most of their match this season, doesn't go that way. It can turned out to be a surprise to u that Real Madrid lost or drew any of their Champions League matches, when everyone thought that they would have 6 points from both matches, taking them to the round of 16.
