I think this season is the beginning of the downfall for Pep Guardiola at Man City after achieving a lot of success with his club now he has to feel the bitterness of going through a slump and pressure from the club, I know the fans love Pep Guardiola very much and the club loves him too but if it continues to decline I think Pep's position as a manager is increasingly unsafe because the club still needs the highest level regardless of Pep having been Man City's successor so far, I think the club will wait for the final results of this season if Man City does not finish in the UCL zone I feel Pep will be fired.
That's why in my next sentences, I said this:
However, if we look back at the results of the match so far for Man City, both in the Champions League (UCL) and the Premier League, this is quite devastating. Just imagine, how clear the list of their match results so far is:
We realize how down Pep and Man City are this season. Especially in UCL, it is not much different from what Real Madrid experienced in UCL, but the difference is, Real Madrid is still better in La Liga. Well, in the next 2 matches, we will see whether Man City can at least be in the play-offs or not.
Real Madrid will definitely qualify to the round of 16, because they are playing two weak clubs to complete their matches. If you have observed in their last two matches, you will see that they are improving in performance and it will continue like that till they pick form. I believe that Madrid difficult times are over, and this is the time for them to start kicking asses.
With Real Madrid's current position in 20th place, then most likely the play-offs scheme or result simulator will be like this that will be faced by Real Madrid. However, all that will change if Real Madrid's position also changes. This will depend on the results of the next 2 matches where Real Madrid will face RB Salzburg and Brest.
