If Napoli can return to their best performance when facing Barcelona, it will be a more interesting match. The current situation may be unpredictable but looking at Napoli's game, more people favor Barcelona to qualify.
The division in the last 16 of the UCL this season is very interesting. There are no favorite teams to meet at the start, maybe only Inter and Atletico. but others may have better chances.
All the teams in the top 16 are strong, but it all depends on the team's condition and readiness for the next match. we will look forward to the big teams meeting in the top 8.
Likely Napoli won't eliminated early in Champion League and they want get back top performance, have 7 matches later before facing Barcelona in Champion League will be chance for Napoli get back their top performance. Barcelona performance not really quit well and they faced much problem exactly with key players injured will make difficult for preparing teams against Napoli on 16 phase next two months later.
Interested match between Inter Milan vs Atletico Madrid because both teams on good performance, Inter managed top position but sadly have to face strong team on 16 round because loss from Real Sociedad to manage top position, its not easy for Inter although on first standings in domestic league against Atletico Madrid have victory trend in last several matches.
Napoli are not really good this year,they did their best last year,but have been in a very poor form this year because some of their players left,and also because they feel they have achieve all they wanted to achieve.Their champions league games is what they want to take serious because they have the ambition to win it,but I know that is going to be impossible because they aren't better than most of the teams in the champions league,a team like Madrid,Arsenal,Mancity,Bayern are teams they can't win because they are the teams that have the better chances of claiming the tittle.I really can't wait for the champions league games to start.
