Real Sociedad failed to find a clinical touch in front of goal in a disappointing 0-0 Champions League draw with visiting Salzburg on Wednesday, but remained top of their Group D having already qualified for the round of 16.

Clear-cut chances were few and far between in San Sebastian with the best falling to Sociedad's Benat Turrientes and Brais Mendez whose efforts were deflected wide and saved.

Sociedad, in the Champions League for the first time in a decade, top the pool with 11 points from five games, level with last season's runners-up Inter Milan. The two sides meet in Italy in their final group game on Dec. 12.
