I wouldn't say that Barcelona's performance was good last season. Only Barcelona and Real Madrid compete for the La Liga title. Other groups lag far behind these two groups. However, Girona's excellent performance last season surprised us all.
However, Barcelona need a stronger squad if they want to dominate La Liga next season. Currently, if you compare the teams between Madrid and Barca, Barcelona will be far behind. I look forward to seeing what steps Flick takes to strengthen this team. Hansi Flick is a very experienced coach.
I can’t deny that Barcelona did not perform well last season. But the way you said it is like Barcelona performance was very poor, which is not, although I can’t argue that Girona did well in their matches until they faced a defeat from Real Madrid and their performance started declining, and from then Barcelona took the place, so to me, Barcelona performance was not that bad last season; they came to the top 2 of the table, which is not a bad result for them.
I think they just need to get new talented players that can give them what the team wants because some of the Barcelona players are weak and they need replacements before the next season kicks off; if not, they will face hard times in their squad.
I deny the fact that Barcelona did not perform well last season. Barcelona performed well, but the truth is that it was not up to people's expectations. Barcelona ended La Liga in second position on the table, so a team that did not perform well would not end the season in second position. For other competitions, like the Champions League, they also tried their best because they made it to the quarter-finals. So, Barcelona was not really that bad last season, but the truth is that they did not play up to fans' expectations.
Barcelona really needs to sign some players so they can strengthen their squad. I believe if Barcelona can sign more talented players and add them to their squad, there will surely be a change. Let's just continue to see which players Barcelona will sign, but the truth is that they must sign good players if they really want to compete with Real Madrid next season.
