Athletic Club host Real Sociedad at San Mamés Stadium on November 1 in Regular Season Round 11 of La Liga.

That is ten goals scored and five conceded across those games, which points to an open, high-scoring side. Athletic Club's league run has been tighter and less decisive. They drew 0-0 at Rayo Vallecano on October 10 and 0-0 at Valencia on October 17, lost 3-1 at Levante on October 21, then beat Getafe 4-0 at home on October 25. Three clean sheets in four league games show defensive solidity, though the lack of goals in two of those matches shows how hard they have found it to break teams down.

Schedule load is a secondary consideration. Real Sociedad played in the UEFA Europa League on October 15 and October 22,
