Iniesta & Messi return to Barcelona squad for UCL clash against Chelsea.
The list is as follows: Ter Stegen, Cillessen, Piqué, Rakitic, Sergio, Iniesta, who has been given the all clear from medical staff, Suárez, Messi, Dembélé, Paulinho, Paco Alcácer, Jordi Alba, Digne, Sergi Roberto, André Gomes, Aleix Vidal, Umtiti and Vermaelen.
The players missing are midfielder Philippe Couthinho who is ineligible after having played in the competition previously for Liverpool and the injured Nélson Semedo and Denis Suárez.
World Cup winner Iniesta had been struggling to recover from a hamstring injury in time to face the Blues in the last-16 second leg, with coach Ernesto Valverde conceding playing the veteran midfielder would be a risk.
But he has decided to include Iniesta in the group for Wednesday's match, where the 33-year-old could feature for the first time since suffering his ailment against Atletico Madrid in La Liga on March 4.
Messi was also missing for the weekend win over Malaga as his wife gave birth to their third child Ciro, but he was expected back and also returns.
Messi scored an equaliser at Stamford Bridge in the first leg as Barca held Chelsea to a 1-1 draw, after Willian had opened the scoring for the hosts.
