On Sunday, Barcelona will visit Estadio Anoeta where they have failed to record a win in almost decade. The last time the Catalan club managed to beat Real Sociedad in San Sebastian was in May 2007, where Andres Iniesta and Samuel Eto'o both made the scoresheet. In their last six LaLiga meetings at the stadium, the Blaugrana were beaten five times, with the remaining game ending in a draw. MARCA take a closer look at each of the six fixtures:
2010/11: Real Sociedad 2-1 Barcelona
Real Sociedad ended a run of 31 games unbeaten in LaLiga for Pep Guardiola's Barcelona. Despite going behind after Thiago struck, Sociedad clawed their way back into the game and recorded a famous 2-1 victory.
2011/12: Real Sociedad 2-2 Barcelona
This game marks the only LaLiga point Barcelona have recorded at Estadio Anoeta in their last six meetings. It seemed Barcelona had surely won the tie after going 2-0 up, but two quick-fire goals courtesy of Agirretxe and Griezmann denied the Blaugrana three points.
2012/13: Real Sociedad 3-2 Barcelona
Goals from Messi and Pedro had put Tito Vilanova's Barcelona 2-0 up, but this time they would go on to lose. Agirretxe found the net in the 91st minute to win the game after two goals from Chori Castro had brought Sociedad level.
2013/14: Real Sociedad 3-1 Barcelona
Messi was on target yet again, but an own goal from Alex Song, coupled with goals from Griezmann and Zurutuza, meant that Tata Martino had also failed to break the Anoeta curse.
2014/15: Real Sociedad 1-0 Barcelona
In controversial circumstances, Luis Enrique decided not to field Ivan Rakitic, Neymar, Dani Alves and Lionel Messi in this game. An own goal from Jordi Alba almost cost the Asturian coach his job, as Barcelona were resigned to yet another defeat against Sociedad away.
2015/16: Real Sociedad 1-0 Barcelona
Mikel Oyarzabal's effort was unanswered when Luis Enrique's side travelled to San Sebastian in the 2015/16 LaLiga season, a defeat that caps off a string of poor results in recent history for Barcelona.
