If people are a bit pessimistic about the season, we're more likely to have success :) It's how it works.
After 16/17, many didn't believe Pep would be a big success in England. In 20/21, after the first 7-8 games, many were thinking Pep's finished (here). There were many bullshit posts in Pep's thread after that draw with WBA in December 2020. What happened after the draw? 21 consecutive wins, that's what happened, plus the title and the league cup.
In 21/22, after we failed to sign a striker, many predicted a poor season. What did happen, though? Best attack in Europe and the title, that's what happened.
Generally, fans are not good at predicting the future, let's be honest here. We expect to struggle in defence because we don't have a specialist at LB (and Laporte is not that good), and then we finish the season with the best defensive record in spite of a defensive crisis. We expect to struggle in attack, and we finish the season with the best goal tally in the world.
The amazing part is many don't learn from their rubbish predictions and worries. Or they learn from them and continue to make them on purpose: to not jinx things?
Anyway: you don't know the future and overestimate your ability to predict it. Calm down and trust in the club. Many fans would kill to watch KDB, Haaland, Foden, Rodri, Bernie, Grealish, Alvarez...in their team with Pep as manager. Our fans are very lucky these days.
