I don't think that Barcelona is a heavy favorite in this match against Napoli.I know that Napoli is in a weak form during all this season in their domestic league but it is exactly this fact that makes me think they will give it all in this game and hope to pull something out of this game as they play for almost nothing in their domestic league.Barcelona is in a better situation and has better players so this will be a very interesting encounter.
It is impossible to predict which team will win this match. Because both Napoli and Barcelona are in the same situation now. Barcelona's performance is quite erratic, as well as the performance of Napoli's players. This team is not performing well in Serie A. Napoli's attack in particular is quite weak. On the other hand, Barcelona's defense is weak. This is why it becomes very difficult to make predictions about this match. Both teams have equal chances of winning. I will not bet on this match. But I think the Barcelona team will be able to beat Napoli. Xavi's only target now will be to perform well in the Champions League.
