If only comparing Barcelona with Napoli, it is clear that Barcelona will still have a good chance of winning by beating Napoli . Because indeed,at least Barcelona still has a good situation and conditions compared to Napoli this moment and therefore, I personally believe that Barcelona will still be able to qualify for the quarter finals .But unfortunately, if I consider thequality of Barcelona at least in a few seasons and not just about this season then ya, at least Barcelona is still not strong enough to be able to go further . Therefore,I think meeting or playing against Napoli in the round of 16 is lucky for Barcelona because and that way, ofcourse Barcelona has a chance to qualify for the quarter finals.
comparing in terms of player performance, maybe Napoli is slightly superior, but if we compare from experience, I prefer Barcelona who will qualify for the next round this is just my assumption.
and indeed experience is not a guarantee, but at least a team that has greater experience in the UCL will have a greater chance of qualifying because of course there are key players and a great coach who will certainly be able to repeat the strategies that must be carried out to get through to the next round whereas if I comparing Xavi experience with Mazzarri, I think Xavi is more experienced to be able to take his team through to the last 16.
I realize that my assumptions may be a little exaggerated, but the fact is that Napoli are not doing well.
