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.
Barcelona's current form will not make it difficult for any team to win or even draw their next Champions League game. Barcelona has been playing very badly this season, in any competition Barcelona will not raise any trophy this season. How did you think that would be possible for them succeed? No, I don't think so, Barcelona used to be ahead of Napoli during the Messi era, but that is not anymore. I think they believe that their striker is the problem, and after signing a new striker, I don't think Lewandowski will have many opportunities in the club anymore. I know Napoli is struggling to win their matches in Italian league, but I think they are going to win in the upcoming round 16 match between Napoli vs Barcelona.
Given that they will be playing with their current players, I think Napoli will give it their all to defeat Barcelona in that match, both at home and away. Barcelona could have given up to a team that is playing better this season, but they can give it another try next year.
