That price looks a little short though, considering Sociedad have only won one league game in front of their own fans so far this term.
The visitors are 29/10 (3.90) outsiders to come out on top at Estadio Municipal de Anoeta, a result that would lift them into seventh place.
Espanyol have only claimed three points in one of their nine games away from home this season and that solitary win came at bottom club Huesca. In fact, the visitors have lost six of their previous seven overall in this competition.
With such patchy form on both sides the most appealing option from the match odds is undoubtedly the 11/5 (3.20) with 888Sport about a draw but there's a better bet elsewhere.
Despite a trend of goals at both ends in recent games between this pair it makes sense to oppose goals in some form.
Sociedad have scored just 20 times in 18 matches this season while Espanyol have only mustered 19 strikes. That leaves both sides ranking in the bottom seven of that metric in La Liga this term, although they've both played a game fewer than the rest of the division.
Defensively though, Sociedad are flirting with the elite thus far. 20 goals conceded means Imanol Alguacil's men have the joint-fifth best backline in La Liga, level with league leaders Barcelona and high-flying Sevilla.
Espanyol are in the bottom half of the table in terms of goals conceded but they've only leaked 24 times themselves, even after such a poor run of results before the winter break.
Taking the last five La Liga games these teams have played combined, "No" on Both Teams to Score has paid out in eight of the 10 matches. At 17/20 (1.85) with 888Sport it looks the way to go once more as two teams who struggle in the final third go head-to-head.
