A frustrated Sergio Busquets hit out at the inconsistency of referee Javier Alberola Rojas and questioned why Barcelona did not benefit from a VAR review, after they were denied an injury-time penalty in a thrilling 2-2 draw at Real Sociedad.
Fourth-placed Sociedad were good value for their point against the reigning La Liga champions, which was earned through Alexander Isak's 62nd-minute strike after Barca had come from a goal down to lead.
However, the visitors felt they should have had a late spot-kick when Gerard Pique claimed his shirt had been pulled by Diego Llorente as the pair fell to the ground in the Sociedad box.
