For the match against Salzburg I am not too worried, Real can win the match easily because as we see in the standings and also their overall performance, Salzburg is far from a team that can make a surprise especially in this match Real as the host. What I am quite worried about is against Brest, I think Real will have a little difficulty, Brest has performed very well in the UCL. But the point is that Ancelotti troops must get 6 points so that the chance to qualify for R16 can be guaranteed even though they have to go through the play-off round.
That match should be an easy win for Madrid because are the best team in the Champions League history, and they have been doing really well some seasons back, but they are struggling to get a perfect consistency this season in the Champions league, but the team had recently improved which is why I am hoping they can easily win because they really need to win their last two matches in order to make it easily to the knockout stage.
There is no easy match for Real Madrid this season especially in the Champions League if they underestimate the weaker clubs usually the weak clubs will give fierce resistance and can give a surprise, hopefully Real Madrid can dominate the match and can beat the teams with all their might they must try to restore their best performance in order to continue to compete in the UCL, Real Madrid is the best club in the UCL they should survive longer and reach the final.
