for now, barcelona is one of the clubs with the best squad in the world so if they intend to buy players again, it's just a waste. What Xavi has to do right now is focus on making the current squad work very effectively. they must be able to at least win a domestic trophy in the following season and the UCL is one of the trophies that Barcelona must target.
If I look at the world club ranking, Barcelona is ranked eleventh. Although this does not describe the strength of the team, but at least you can certainly think again to call Barcelona the best club in the world. The current number one is Man City. So if you want to judge then you should be in a neutral position. I think the season Man City in the Best Club in the world.

Because after all, in reality Barcelona has experienced more failures such as failing in the Copa del Rey, failing in the Champions League and even worse, even though Barcelona still has a good chance because it is playing in the Europa League, but Barcelona still fails. With results like that, it is certainly not correct to say that Barcelona has succeeded this season, because after all Barcelona is only focused on La Liga, while in reality Barcelona has a good squad.
