Suarez and Sergi Roberto were both sent off in the second leg of Barcelona's semi-final victory over Atletico Madrid and consequently miss out this evening as Enrique makes four changes to the side which beat Eibar on the final day of the season last weekend.
The match will be Enrique's last in charge of Barcelona before he takes a sabbatical, and the Spaniard could win a ninth trophy of his three years at the helm with victory.
Barca have won the competition for the past two years, but Alaves are appearing in their first ever Copa del Rey final and their first major final at all since their 5-4 extra-time defeat to Liverpool in the 2001 UEFA Cup.
Barcelona: Cillessen; Umtiti, Mascherano, Pique, Alba; Rakitic, Busquets, Iniesta, Messi, Alcacer, Neymar
Subs: Ter Stegen, D Suarez, Turan, Digne, Andre Gomes, Vidal, Marlon
Alaves: Pacheco; Femenia, Feddal, Vigaray, Ely, Hernandez; Llorente, M Garcia, Gomez, Mendez; Deyverson
Subs: Ortola, Alexis, D Torres, Camarasa, Romero, R Sobrino, Toquero
