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.
Barcelona and Napoli are both in bad condition at the moment.
I think experience is quite important in UCL matches because this is a high-tension match that requires a strong mentality.
I see that the strengths of Napoli and Barcelona are not much different from all sides so in my opinion the percentage of the two teams to qualify is still very equal.
