I also think so, overall Real Madrid's performance this season is very inconsistent and also the matches in UCL cannot be underestimated especially overall the strength of RB Salzburg and Brest is not that bad this season so it is also possible for RB Salzburg and Brest to make a surprise when playing against Real Madrid later.
I think everything is possible in the remaining 2 UCL matches before the playoffs later and I think Real Madrid cannot be favored excessively.
One thing that should on check in this last two matches left by every team, even those teams that are looking not too strong and playing against the big teams will also be fighting in order to get a spot in the playoffs even though they can’t make it to the next round directly. Playing in the playoffs will be like a big record to them than it will be for this big teams, so all big teams trying to survive this stage to the next round will be more careful in the remaining matches. Their fixtures may look very cheap but in reality of the champions league, no need can be underestimated and they should play and treat all teams equal if they really want to go far in this competition.
No match looks cheap, such a notion in relation to clubs that play in the Champions League seems incorrect to me. Every club that competes in the Champions League has qualified for this tournament by winning or vice-championship within their championship, it certainly cannot be called cheap or moreover to call such a team weak, it is simply incorrect. Just within the Champions League teams of completely different levels and each team looks different against the background of the other team
