Talking about the match between Napoli vs Barcelona the odds for both of teams are equally same @2.55 but actually a bit hard to predict the outcomes of this match because the condition between them is not so different that at their domestic league these teams is still struggle want to return to the winning ways and their performance at champion league also not so impressive because both teams have experience to lose twice even Barcelona have to lose on 6th matches against weak team Antwerp
Both teams has been met several times at Champion league and Europa league and Barcelona records was slightly better than Napoli because they were unbeatable in the last 5 meetings but currently Barcelona have a problem with their forward lines because after Lewandowski performance was decline then Barcelona performance seems very unstable but for the first leg i am sure Napoli as a host will attempt to beat Barcelona but just like i said before with their current conditions it's hard to beat Barcelona even for this match i was start to thinking possibly will ended to draw
I still think that Barcelona is a better team overall, I am not saying it is a clear cut situation, I mean they are definitely close and I do not disagree with that, but I wouldn't really make it equal odds neither. I would make it like Barcelona is just a little bit better, like maybe 2.30 to 2.80 odds or something, that would make a lot more sense, it is a smart move for sure.
I believe Barcelona has a better squad and a better manager as well, but they do not have the chemistry that Xavi requires for this tactic to work, if the team doesn't have the perfect chemistry then the tiki taka method doesn't work at all, they do have some players showing promise, but some of them are not used to this style so having trouble.
