Basically Napoli are still playing well in Serie A and I feel, Napoli have the strength to be able to win this match. Unlike Barcelona, which is still making improvements and uniting players will certainly not be easy, while at the same time Napoli only need to maintain their well-formed performance at the start of the season. With this comparison, I personally feel for now that both of them do have a chance to win and this is still not easy to predict.
In my opinion, the strength of both teams is equal now. Napoli have only maintained their consistency. But the Barcelona team has improved themself. They are improving day by day though. But at this moment we can not call the Barcelona team weak. The team is strong enough and Barcelona has the ability to beat Napoli. However, Barcelona will have to stabilize the midfield.
