Sevilla have made six changes to their side that was beaten at the weekend. Vaclik comes into the side in place of Yassine Bounou. Vidal and Acuna start in the full-back positions ahead of Navas and Sergio Escudero, who misses out tonight. Suso, Torres and En-Nesyri get the nod in the final third as Gomez, Munir and Rakitic drop to the bench.
Koeman has opted to remain the same team and formation that was successful against Sevilla at the weekend. Messi and Dembele lead the line in the final third with Dest and Alba operating on the flanks. Pedri and De Jong are operating in support, with Busquets sitting in front of a back three.

Sevilla were off the pace in their 2-0 defeat to Barca last time out. Their form has been up and down since beating the Catalan club in the first leg, recording league victories over Huesca and Osasuna, but also losing the first leg of their Champions League clash to Borussia Dortmund and then again in their contest with Koeman's side. Discipline is the name of the game for Julen Lopetegui's men this evening.
Barcelona start the night needing to overcome a 2-0 deficit to advance to the final of the competition. They were outplayed in Seville as goals from Jules Kounde and Ivan Rakitic condemned them to defeat. The two sides did meet at the weekend in LaLiga where Barca got their revenge on the road as goals from Ousmane Dembele and Lionel Messi secured the three points. However, Ronald Koeman and his men know that they face a tough slog tonight.
Good evening and welcome to the live commentary of the second leg of the Copa del Rey semi-final clash between Barcelona and Sevilla at Camp Nou.
