I predict Napoli will be eliminated after the second leg match, I compared it to when Napoli played in the first leg, there was nothing special and they can only make 1 shot on target even though they were playing at home and the goal was lucky. I can't imagine what Napoli will do in the second leg match and Barcelona as the home team is certainly more aggressive than the first leg match, I'm a little doubtful that Napoli can score a goal.
I'm not sure what you're saying and I actually think that Napoli can beat Barcelona in the second leg. This is not a matter of Barcelona being favored because they are playing at home, but with Barcelona's record of home games which so far has not been very convincing, it makes me say that Barcelona's chances of winning are only slim and on the other hand, Napoli has a pretty big chance of winning.
I understand however that Barcelona will be much better when playing at home but unfortunately for the Champions League the case is quite different and they cannot necessarily be relied on to win against Napoli. As for other results, it is possible that the match will end in a draw again and force both teams to go into extra time or a penalty shootout. I think that's quite appropriate considering that the two teams are in almost no different form. Apart from all that, I hope that both teams can play freely without having to rely on luck in the future.
