There is no doubt that Real Madrid is the best team in Europe due to the achievement they have gotten in European competitions but let us not hype them too much because that was how Liverpool was hyped and they were knocked out of the Europa league by Atalanta so sometimes, club goes through some difficult challenges even when they meet a lesser opponent
I don't think the depth of your judgement as stated is enough to already see Real Madrid as the best team in the whole of Europe, if it's by achievement, i know they have been able to achieve quite a whole lot and they are deserving of every of it because they have been able to show through their performance in the fact that they deserved all of that which they have gotten over the years as they have been participating in the competitions.
The strength of a team is usually very relative a d that's in the fact thst there are areas where they have got strength and aswell area where there's also to be seen weakness to but them been able to exercise their strength over their weakness isn't a guarantee or enough to see them as the best team and that's why i think it's a perfect idea to make it seasonal probably they could be this season and next it may go to another team because there are team that looks better in some season a d the other they are looking worse than you would have expected of them.
It's not even about the hype, they could be hyped and still win the trophy and still not be Hyped a d still not win so either ways they are only good if they are at the point in time and they should just enjoy it while it lasts, because there was actually a time when they weren't such good but then at this point they are as it's still very possible and
