The Chile international has being plagued by muscular problems, but is widely expected to feature in Saturday's La Liga fixture against Phillipe Montanier's outfit
The Chile international picked up a muscular problem in the 1-1 Copa del Rey draw against Valencia in midweek, and there were doubts about the 23-year-old's availability for Saturday's game.
Nevertheless, Blaugrana medical staff have now allegedly given the South American the green light to feature in the match against Phillipe Montanier's men.
The former Udinese star has been in superb form for the Catalans since his summer move to Spain, netting seven times in 12 La Liga appearances.
Saturday's match at Camp Nou kicks off at 22.00CET.
