This is not a time for blame games and Messi should not be seen as the main problem in the club. Only Messi cannot do it alone and needs the collective support and efforts of other players in order for the team to succeed. Messi was just a pivotal player in the midst and can change the game but when he tries and the rest of the squad cannot add their own effort, his own effort becomes useless and the whole team will fail again and again.
I think this year flop was due to injuries of their key players even the ones that were playing just recovered from injuries so it was an injury season for the team not to mention of their financial problem to bring in good players... I think Messi was never their problem...just that Messi was a feared name in Barca whenever they face any opponent
Barcelona currently needs time to recover from its downturn, especially with a new coach and financial problems. Of course, Barcelona in the UCL League next season is considered not to be the favorite in the race for the title. I will prioritize Real Madrid and Man City in the fight for the UCL title next season because these two teams have very good squads compared to other teams and have great coaches.
