I think it will be a match week where all three teams will win. Of course, Real Madrid will have a very difficult match because they have to rest their players for the Arsenal match. If they do not rest their players, they will not be able to find that little hope in the Arsenal match. If they do not take the field with their main squad, there is also the risk of losing points. Of course, Real has a very good squad, but small teams can always be challenging.
Ancelloti will not take any risks in this match and I am sure he will not rotate players at the start of the match because this is also a big match that they need to win in order to get full points. Real Madrid are in a bad form because they have had some bad results in several matches so in this match he needs to field the main squad in order to maintain the chance of getting three points. While the other two clubs will probably get full points because they don't face many challenges at the moment although later they will also experience a little difficulty.
The problem is that sometimes things like this actually weaken Ancelotti where he sometimes applies tactics that make the situation unexpected and end up in uncomfortable conditions for Madrid.
As happened when they met Valencia where he tried to make some adjustments to the club who did try to pair a new goalkeeper and some players who in my opinion are currently in declining form which makes what should be a victory because they are trying to keep up with Barcelona actually ended in defeat.
They are currently in a downward spiral especially mentally where they lost in La Liga and they also crumbled at the hands of Arsenal in the Champions League. Obviously this is a situation that could not be handled properly in the future if their performance remains the same, especially now that the pressure of 3 points is clearly a must that they must get in the continuation of La Liga if they are still eyeing the trophy at the end of the season as their ultimate goal.
