Real Sociedad are a much stronger team than the side that beat Barcelona while David Moyes was in charge, on January 4, 2015.
They are stronger still than the team that beat the Catalans again earlier this year, in April.
For the first time in a long time, there is not only spirit and fire in abundance in San Sebastian but substance, too.
And that spells bad news for Barcelona, who have not won away there since 2007, when Frank Rijkaard was in charge and his team earned a 2-0 victory.
These are the games between that have taken place since then at Anoeta, with Real Sociedad returning after relegation to the top flight in 2010:
09/14/16: Real Sociedad 1-0 Barcelona
04/01/15: Real Sociedad 1-0 Barcelona
22/02/14: Real Sociedad 3-1 Barcelona
12/02/14: Real Sociedad 1-1 Barcelona (Copa del Rey)
19/01/13: Real Sociedad 3-2 Barcelona
10/09/11: Real Sociedad 2-2 Barcelona
30/04/11: Real Sociedad 2-1 Barcelona
