Manchester City performance is also poor in domestic league if not they should be among the top three clubs on the table. I believe that City will not survive from the playoffs, because in history Real Madrid haven't been kicked out from the group stage, and I don't think that will happen this season. Real Madrid is the best club in UCL and they have won it 14 times, for this reason, I have confidence in them.
City's performance is sometimes good, sometimes it's not and of course, due to its performance which is always less consistent in winning, of course, City in the EPL is not good enough and in the end they can only finish in 5th place in the standings, indeed if for example City can finish in 3rd place, that's true. good and will definitely be respected by the UCL team. but personally, at this time I cannot conclude that Man City will lose because, however, City has still won a trophy in the UCL and it is possible that Pep Guardiola will be able to train Man City players to be better when competing against Real Madrid.
but it could be that your guess is correct and indeed Real Madrid is of course more experienced in the UCL because they have won many trophies in the UCL and of course if for example Real Madrid does not get a ticket to the last 16 of course it will make Real Madrid embarrassed because of course Real Madrid's reputation will fall if for example that happens. But on the one hand, Man City could be mentally superior because City players will definitely think that even if City loses, Man City will definitely not be embarrassed because the one who beat them is a club that always wins trophies in the UCL.
