It is true that Barcelona have managed to strengthen their squad this season, they have very talented and very experienced players in the squad now so it is expected that the team will play better and compete for all titles this season. The addition of Dembele, Raphinah and Lewandowski have improved the squad, boosting the attacking options and have transformed the team to a better goal scoring team.
Agree. But don't forget that they have a great coach, too.
Having talented players may not be effective if they have no good coach, it happened previously.
This season, Xavi as the coach, really changed Barcelona squad. He can choose proper players in the last transfer window, such as Lewandowski, Raphinha, or Kessie. These new players give a big impact on the squad. Barcelona attacking looks very sharp, and they have a solid defense as well. Sure, this team become one of the most productive team in scoring this season.
