Barcelona have confirmed the 18-man squad to play Arsenal, with Gerard Pique suspended but Arda Turan back.
Arda missed the first leg in London due to suspension but he is free to play at Camp Nou and some reports from Catalonia have named the Turkey international as a potential starter.
Pique is missing after he was cautioned in the first 2-0 first leg win and ex-Gunner Thomas Vermaelen has been touted as his replacement.
There’s no place for Adriano, Douglas or goalkeeper Jordi Masip, and Rafinha and Sandro Ramirez are injury absentees.
Barcelona squad to play Arsenal:
Ter Stegen, Bravo, Alves, Vidal, Vermaelen, Mascherano, Bartra, Mathieu, Alba, Busquets, Arda, Rakitic, Iniesta, Sergi Roberto, Munir, Messi, Suarez, Neymar
