Barcelona is certainly playing very well and their game is also getting better. At the start of this season, Barcelona played well against Mallorca with a score of 3-0. Of course, Mallorca was unable to score a single goal against Barcelona, this certainly shows Barcelona's strong strength.
Barcelona coach has put more effort to make sure their performance improve which is what people are seeing in Barcelona this season, because they secured victory from their first game to send signal to their fans how this season will look like. For Mallorca not to score single goal from the game that ended up 3:0, show that Barcelona will still repeat what happened last season to lift la Liga league trophy this season, because they are well organized to beat any
teamclub that will come their way.
I know that is too early to predict who will lift this la Liga league trophy but seeing what Barcelona display and what Real Madrid display from their first game, show that Barcelona will not face any difficulty opponent through out this season.
