Dembele returns to Barcelona squad but Messi & Suarez won't go to Vigo
Valverde has also left Deulofeu out of the squad
Iniesta will also rest as Aleña and Arnaiz come in
Ousmane Dembele returns to the Barcelona squad for the first time since Septmber for the Copa del Rey game against Celta Vigo at Balaidos.
However, Ernesto Valverde has decided not to call up Andres Iniesta, Luis Suarez or Lionel Messi.
The presence of Dembele, the club's record signing, is the big attraction in Valverde's squad for the first leg of the round-of-16 tie.
Suarez and Messi only returned to training on Tuesday following an extended Christmas break in South America and will not be risked in Vigo.
Valverde has also left out Gerard Deulofeu, who has not featured much in recent weeks, Rafinha and Arda Turan.
Paco Alcacer and Samuel Umtiti are the only players currently missing with injuries.
The squad is: Ter Stegen, Cillessen, Semedo, Piqué, Rakitic, Busquets, Denis, Dembélé, Mascherano, Paulinho, Alba, Digne, Sergi Roberto, André Gomes, Aleix Vidal, Vermaelen, Aleñá (26) and Arnaiz (37).
