In the new season at Laliga, Barcelona will again get strong competition because rivals Real Madrid understand what failed last season, and of course, it will be a heating season because mistakes made by one of them will benefit their competitors, and it looks like Laliga is back will be domination for Barcelona and Real Madrid.
Barcelona have so many talented players, the problem is just the coach. It's very rare a good player can become a good coach, same like Xavi Hernandez. What make Barcelona strong is because of high individual skills, the team play and strategy aren't different from one to another match.
Although Barcelona able to win the last season La Liga, it's an achievement, but they're still not developing.
I think you're right about the squad's improvement because we all know that Barcelona is a team with brilliant players who are very strong and good goal scorers. I think the squad won't be eliminated from the champion league's starting lineup so easy if they have a successful season,but As I see it presently teams like Real Madrid and Barcelona are going to be strong in the upcoming LA Liga season. This is because both teams have recently signed young, talented players who are extremely intelligent, and this indicates that there will be a challenge.
Due to my observation, there are no other teams in laliga that have signed many talented players this season than Barcelona. As a result, it will be beneficial if Barcelona performs well in the champion league the following season. If Barcelona fails to try to reach the semifinal or final stages of the champion league the following year, it will be very challenging for them to win the champion league.
There's no doubting the potentials of Xavi Hernandez's Barcelona and how outstanding they can be against against their opponents in not just domestic matches but also in European scene.
But I think Real Madrid will be careful and calculative than they were last season. Madrid would definitely work on those factors that made them to lose the Spanish La Liga title to Barcelona last season and the fact they have added more few quality players in the squad gives them an edge over the La Liga rivals
