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 a gree with you. Napoli played at home but they couldn't maximize their advantage in the first leg. As you said Napoli's game was not that good. But at that time Barcelona's performance was also not good but they managed to get 6 shots on target. They couldn't convert several opportunities into goals. But it will be different in the second leg because they play as hosts. Barcelona can also learn from the draw in the first leg. I bet Barcelona will win and will qualify for the next round.
I think Napoli's performance has dropped drastically. They had a very impressive performance last season but this season their performance has been inconsistent and they have had to struggle in the middle of the table. So it is not surprising that they cannot get maximum results against Barcelona. This draw provided quite a big advantage for Barcelona because at that time they will play as host. But that doesn't mean that Napoli has already lost their chance because anything can happen in football and it often provides unexpected surprises.
