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.
