Barcelona in UCL does not have a significant burden because it could be said that group H does not contain strong teams. They can easily qualify from the group phase, but in the future I think Barcelona will have difficulty making progress because Barcelona has many injured players and several players need to restore their rhythm, Barcelona cannot perform much better even in a difficult situation for the squad.
In La Liga, maybe it depends on Real Madrid's consistency. If Real Madrid cannot maintain its consistency then Barcelona has the opportunity to compete for the league championship. We know that in La Liga these two teams will definitely be chasing each other to get points, it's true that La Liga is still long but the habit looks like it will continue.
I think Barcelona are just lucky to be in a less competitive group, facing no threats from teams, rather they keep their high voltage in every match they play in UCL but for La Liga matches, it's definitely going to be a tough struggles for them, losing yesterday in El Clasico against Real Madrid. Barcelona will qualify in their group H because there's no entertaining actions from their opposition. I'm scared Barcelona will not do well this season, having absolutely nothing to offer but due to injured players in the main team. Xavi Hernandez will create path for his team because he's keen on achieving good points on the table.
I do agree with you. The different thing when barcelona will be competing with some strong clubs like manchester city or bayern. I think that we will be seeing how good barcelona when it will be facing strong club. People are being overreacted with barcelona caused by it was only winning in the easy group like that. It must be noted that if the performance from barcelona may be going down so hard after this. Barcelona is not that good with so many young players.
The club is still lack of quality compared with some clubs that have so many great players like bayern or manchester city. Barcelona may perform so poorly when it will be facing great club.
