The two teams return to the competition with the tie level at 1-1 after the first leg in Italy, but Barca do have the slight edge due to home advantage and the away goal.
Santos, who left the Camp Nou for Sassuolo in 2018, has faced Napoli twice this season with the Neroverdi and knows all about their attacking quality.
“They are a great team but Barça are favourites. Barça must be careful though because Napoli have a lot of dangerous players, especially in attack, like Milik and Mertens. But Barça have the best player in the world and I think they’ll go through.”
