I don't think there's anything wrong, because this is just an assumption or prediction that is made. Maybe I would say it's wrong when someone claims with certainty that Real Madrid will retain the La Liga title and also the Champions League. If it's all just an assumption, then I think it's valid.
You're right that they're not as consistent as last season, but they still have the potential to be more consistent. The opportunity is on them, it's just a matter of how they can be more consistent.
In a prediction, we can't say it's wrong or right, because what is seen is the result of analysis, so it could be that it doesn't happen and it could be that it happens.
I was wrong, the assumption could be anything. You're correct that except the person says it is certain that it will happen it cannot be disputed. Real Madrid is still competing for both trophies which means they can be fortunate to win both. If they can be consistent in their performance from henceforth, they can achieve it, after all they have enough good players.
The defensive line of those who have a little problem such as Carvajal who suffered injuries and of course some other defenders too, this suppresses the ability of Real Madrid in defense, even though we think that midfield and also the Real Madrid front lines have potential players and are also good but also Did not rule out the possibility that their survival line would be very difficult for them to be able to get a perfect victory.
I hope that Ancelotti can get back his defense as well as what I often see disappear in this team is a collaboration that often miss communication so that it makes it easier for people to break the attacks that want to be built when fighting a team that is equal or more on it at this time.
