Barcelona drew with the Serie A outfit at the Stadio San Paolo in February but the second leg was moved to August due to the Coronavirus pandemic.
Quique Setien’s men have been poor since the campaign resumed in June, having surrendered a two-point advantage in La Liga as rivals Real Madrid usurped them to claim the Spanish top division title.
Rivaldo, who played for Barcelona during his heydays, believes Napoli could compound the Blaugrana’s misery when they face each other at Camp Nou next month, and insists such a pessimistic feeling makes him worried.
“There’s a real danger, Barcelona can be eliminated by Napoli,” the 48-year-old Brazilian said, according to Italian sports news outlet Tuttomercatoweb.
“As a fan and a former Blaugrana player, I’m really worried about this match and I think most of the faithful are sharing this bad feeling with me.”
Lionel Messi also slammed the Catalans after their passive display against Osasuna on Thursday night, and warned his team-mates to improve before facing the Partenopei.
