When it comes to performance decline, then at least Barcelona and Napoli are both experiencing a decline in performance at this moment . But indeed, although Barcelona and Napoli are both experiencing a decline in performance, at least Barcelona still has better quality. Also, when comparing the quality of the coach, at least Xavi is also still a better coach compared to Mazzarri and therefore,basically Barcelona still has a chance to qualify for the quarter-finals by beating Napoli in this round of 16.
Well, hopefully Lewandowski performance will also improve for the match against Napoli later because after all, atleast Lewandowski is also still a Barcelona goal machine. But ya, the point is Napoli made the wrong decision I guess because ya, Napoli chose the wrong coach to lead in an era like this and it was a mistake.
Barcelona is not in any way in comparison with Napoli even though Napoli has shown some positive results in their last game and even at that in terms of statistics, Barcelona is still very much ahead of them and for sure be in the champion leagues, Barcelona will give many clubs a hard time and a run off for any of their winnings or even draw.
I am sure Barcelona may not lift the championship trophy this season but then there is the possibility of them placing themselves in a good position that can easily propel them to possible success.
I dont really see Barcelona in any good position, they still being a trash, no one is backing them this year, they lack all, this year they also is doing bad in local competition, so for the only thing they can go far his for luck in the draft.
