And why do you think UEFA switched to this system? I think because, with all its disadvantages, it will now better reflect the strength of teams
On the contrary, it won't reflect the strength of the team but instead the current form which is imho a worse thing from the perspective of a fan.
Ummmmm... But doesn't the totality of a team's form at different times show up in its strength = results?
The most important thing is the results, and everything else like “well, in general, we are strong, but we were in bad shape, that’s why we lost” is irrelevant.
And I would like to focus once again on the fact that the results of a team in a separate tournament affecting its position in this tournament are as logical as possible. And the situation when a team’s results in other tournaments affect its position in another tournament is nonsense.
Nobody gives a damn about this tournament but the results are taken into account and this distorts the rating
The right move was to reduce the amount of friendly games instead of making that nonsense Nations League and that way those games would agffect the rating less, but UEFA is of course more intersted in making money instead what's better for football.
Of course, UEFA doesn’t care about anything except money. But in this case, they came up with a good formula that is fair (maybe they were just mistaken
).
