Real Sociedad coach Jagoba Arrasate believes that the next two matches could define the club's season.

Sociedad finished fourth in La Liga last season, but have won just one of their eight league matches this campaign, a run of form that has left them 15th in the table.

However, Arrasate is hoping that upcoming games against Valencia and Manchester United can boost their confidence.

"We are aware we are on a bad run and it's clear that if we have gone so many games without a win then we are doing things badly, or not doing some things as well," he told Marca.

"In the dressing room we've found it difficult to put our finger on it, but we've analysed it. Both Mestalla and Old Trafford are places where if we won it would give us a lot of confidence."

Arrasate took charge of Sociedad in the summer.
