Now the challenge is to finish the UCL in the last 16 against Barcelona, even though historically Barcelona is in superior head to head condition. but this time Napoli has a high chance of stabilizing the players, it just depends on how effective Walter Mazzarri strategy is in overcoming the Blaugrana game.
Napoli have often experienced quite significant defeats from Barcelona when they met in European matches, but I think Napoli can breathe a sigh of relief because the current Barcelona is not as strong as the Barcelona that Napoli previously faced, head to head it could be said if Barcelona is quite superior, but for Now we can see how Napoli in the last few years has become a fairly strong club in the league and is capable of becoming a champion contender, I think for the next match head to head is not a guarantee to be able to underestimate Napoli.
Barcelona aren't having the best of times in La Liga at the moment, but they finished top of their group in the Champions League with 12 points. They had tougher opponents like Shakhtar and Porto. Napoli only had Real Madrid. A dead Union Berlin and almost the same Braga. I think Barcelona have a better chance than Napoli.
