When you look at the performance of this two teams, it is very obvious that they are on the same level now. Their individual performance in both leagues is just the same and nothing much can be said in their upcoming match against each other. One of this two teams will be eliminated from this round and won’t advance to the quarterfinals, the thought of it makes it more interesting to watch out for their match by next year when they meet in the round of 16.
Barcelona and Napoli aren't in the same form right now. In the beginning of the season, Napoli was staggering and trying to stay form but it wasn't later before they were able to build stamina in their domestic League, they are now good and there games so far is improving in every round but look at Barcelona, they were in good form in the begin of the season but right now if they should meet Napoli today, they are going to lose that match because are not in form.
Barcelona is trying to maintain their place in the domestic League where Girona is now the supreme leader on the standing but Napoli is trying to come back to the top and so far it is working for them, they only need to spice things up to break Barcelona into pieces. But if Barcelona later come back on form, there is every chance they can take down Napoli because there last game is giving me loss vibes when they have the chance to beat a small club for Coppa Italia.
