Xavi has managed to bring Barcelona to a better direction even though Barcelona were eliminated too quickly in the UCL and UEL, they must try to make amends in European competition next season.
The truth is that Barcelona don't see themselves in europa and UCL, it has been long they won the Spanish league. After they might have win the Spanish league this season I know they will put better concentration in champions league. A club that has not win the home league for a longtime would want to win it first before any other one.
It's only natural, if Barcelona failed in the Champions League. plus, the europa league. because, Xavi has just built Barcelona's strength back. meaning, there are still many deficiencies that Xavi must correct. also, with available team squad. Xavi still feels that his current team still has shortcomings. therefore, in the next season several other players will be released by Barcelona and several others who meet the criteria they will bring in. at least, in the next season Barcelona can be tougher than before and be able to compete at the Champions League level. plus, some of their younger players will be more mature in terms of experience.
For now, Barcelona is on the path to the La Liga title. meaning, Xavi's focus will be on maximizing his team to remain consistent until the end of this season. plus, maximizing the chances of picking up the Copa del Rey Trophy. at least, they were already half way to the final round match. What Barcelona needs to do is maximize their advantage when they host Madrid at Camp Nou.
