Barcelona conceded 38 goals in the 2019-2020 season. They conceded 38 goals in the 2020-2021 season. In the current season, they have conceded 19 goals in 16 games, which would project to 45 goals conceded over the whole season. I'm not sure how you can consider this an "unforgivable mistake" over such a long period of time. That's just what Barcelona's defense is.
I'm looking at these statistics and finding the result highly questionable.
According to this, Real Madrid, Atletico, and Sevilla should have finished between 10 and 20 points lower on the table than they did.
The entire top 4 bar one team was wildly overperforming these statistical marker.
Don't you find this statistic a bit preposterous?
The best way to have an opinion is to watch the 38 matches of Barcelona, Real Madrid and Atletico.
I've watched every league game for Barcelona and almost all of them for Atletico and Real Madrid.
Barcelona started the season very badly, from the third match to the tenth . Messi was like playing with one less, he didn't defend and he was a disaster in attack. He was not yet mentally prepared after the story of burofax and wanting to leave.
From there Barcelona had an extraordinary streak: 18 or 19 matches without losing with 15-16 wins and 3 draws, 9 consecutive wins away from home and a good goal average. Barcelona also won the CDR during that time.
Barcelona without Messi had very good results: 0-4 vs Dinamo Moscow and 0-3 vs Ferencvaros for example.
And when you could put leader winning at home to Granada then you lose. You start winning 1-0, Messi and another who I don't remember miss 2 clear chances and then 2 brutal defensive errors.
My opinion is that people who did not watch the matches are influenced by many comments in the press and forums. Mainly because Koeman doesn't like him
Barcelona deservedly lost the league due to very serious individual errors repeatedly.
Barcelona's game had ups and downs but overall it was good compared to previous seasons with Valverde.
I repeat, this is my opinion for people who did not watch the matches.
