Although Sevilla arguably need victory on Saturday more than Barcelona in terms of achieving any true success this season, Barcelona's exit from the Champions League has left La Liga champions-elect a wounded lion, and the Valverde's side will be desperate to soften that European blow by clinching the cup to complete a domestic double.
Sevilla manager Vincenzo Montella, right, and defender Sergio Escudero speak ahead of Saturday's Copa del Rey final against Barcelona.
However, their hopes of glory in Europe were dashed last week by Roma, as the Italian club incredibly overturned a 4-1 first-leg deficit to progress to the semi-finals on away goals.
Confidence is surely low in the Sevilla camp heading into Saturday night, but pulling off an upset and beating Barcelona in a cup final would create a very different atmosphere around Seville.
"We have been in a situation before where everyone said we were the favourites but we got lost on the way", Valverde told a news conference on Friday. "It's my first chance to play a final with Barcelona and I'll do everything that depends on me so we can play a great game".
"If we are intense on all fronts and focused at every minute, we can definitely do it", Banega said on the Sevilla club website.
"That game is a clear reference point for us and a warning of what could happen tomorrow", Valverde added. Storming into a 2-0 lead and keeping Barca out for large parts of the game, it seemed to be Vincenzo Montella's day. In the Champions League we were favourites and we didn't go through.
Of course, when a cup and a title is up for grabs, the stars lift their heads and, despite being on their last legs and tired, Barca are fully aware of the job in hand.
The final will take place at Atletico Madrid's Wanda Metropolitano Stadium in the Spanish capital, and there is concern about the crowd's behavior considering the ongoing political turmoil involving Catalonia and the Spanish government over the region's bid for independence.
Guardiola was famously impressed by Iniesta in his teenage years, telling Xavi the that he would "retire us all", and has spoken about the pleasure of managing the virtuoso talent. Two seasons ago, the team lost to Barcelona in the final. Arguably Sevilla's strongest defensive figure, his ability to track the movement of Suarez and keep him quiet could prove crucial to the Frenchman's side's success.
"It is 90 minutes of work, we have to see where we can play, where they might slip up".
