for this season I think it is a bit appropriate to say Barcelona is a mediocre club.
Regardless of what happened in the past, the current Barcelona team has experienced a decline in quality compared to last season with all the problems that exist so that they do not have a big chance of competing to win the Champion League title and that is quite natural when we look at the strength of the Barcelona team far behind compared to the current top European teams.
The team's situation has not been good in the last few seasons with all the problems they are facing, and I think Xavi's departure at the end of the season will make things worse.
Since faced financial problem last several years ago Barcelona decreasing become the mediocre team with their financial difficulty not easy for signing top players every window transfer opening. In football modern era, money is most important how to help one team success break out many trophies every season such as Manchester City won their first Champion League after spending much money for signing many top players.
But Xavi Hernandez keep more promising manager for Barcelona comparison last several manager before since get financial crisis, won La Liga tittle and success for the first time qualified to 16 of round after failure last two season in a row is very good achievement for him although management not support yet until Xavi had leaves his position at the end this season. Get much problem in the next season with Barcelona after Xavi Hernandez's departure I don't think easy to make Barcelona keep on good perform in Champion League or domestic league.
