Miguel Angel Nadal is hoping Barcelona do not underestimate Sevilla in Sunday's Copa del Rey final after describing Unai Emery's men as a "very dangerous team".
Sevilla overcame a 1-0 half-time deficit to cruise past Liverpool 3-1 in the final of the Europa League on Wednesday - claiming the trophy for a third successive year - and former Barca defender Nadal is wary of the Andalusians.
"Sevilla come into it on the back of a very important title," he told Omnisport. "I thought they proved they are a very dangerous team."
Nadal still thinks Luis Enrique's men will prevail at the Vicente Calderon to complete a league and cup double.
"I reckon Barcelona are favourites but this is football and you have to respect every single rival," he added.
"Overall I think a Copa del Rey final is a great game and a great opportunity for Barcelona to get another trophy and finish the season in a great way. A Liga and Copa double is difficult to do and means a great season. Let's hope it's an entertaining match.”
Nadal thinks Real Madrid will edge it but believes Diego Simeone's Atletico "deserve" the title.
He said: "Atletico have a lot of faith in their own style of playing and eliminated important teams like Barca and Bayern Munich along the way. I reckon it'll be a tight game and Real are slight favourites to win.
"If you told me I had to bet, right now I'd probably bet on Real but I think it's a really tight contest. Having said that, Atletico deserve it.”
