Barcelona travelled to Real Sociedad on Sunday night trailing La Liga leaders Real Madrid by seven points.
Sociedad dominated the first 45 minutes against a Barcelona team that failed to register a shot on target.
The hosts deservedly led in the 53rd minute through Willian Jose, but Lionel Messi levelled just six minutes later to set up an enthralling final 30 minutes at the Anoeta.
Juanmi had a goal wrongly disallowed for offside in the 76th minute as Sociedad pressed for a second late on, but the referee brought an end to proceedings at 1-1.
Read how it all unfolded in Sports Mole's minute-by-minute live commentary of the action below.
