but for other matches such as Barcelona vs Napoli, anything can still happen. Because in the first leg they could only play a draw. So in the second leg it is still uncertain which one will be the favorite. It's just that Barcelona as the host seems to be the favorite.
Barcelona certainly won't waste this opportunity to play at home, it will certainly be an interesting match, because in the domestic league Napoli doesn't look good so Barcelona can take advantage of their current declining performance, Xavi must be able to take advantage of that by putting pressure on his players to being able to play optimally and win the match in the second leg, at least a narrow win is more than enough to qualify for the next round.
I am confident that Barcelona can qualify for the next round. It seems they will overcome Napoli at home of course with a different strategy, learning from the failure in the first leg where Barcelona was held to a draw by Napoli, it is clear that this is something that is not profitable, I think Xavi has prepared a strategy which is good for facing Napoli in the second leg match later, my prediction is that Barcelona will probably win 3 - 1 against Napoli in the second leg match later and they will succeed in qualifying for the next round because they are quite worthy of advancing compared to Napoli.
