With a 3-0 advantage from the first leg, Barcelona should progress to the next stage of this season's Copa del Rey tonight as Alaves look to pull off the comeback of the century at the Camp Nou. With their third-choice goalkeeper set to make his competitive debut, I doubt anyone gives the Basque side a hope in hell of reaching the Round of 16, and if anything, it's simply a question of how many Barcelona score tonight - and of course who gets the goals with Lionel Messi watching on from the sidelines.
