Mikel Oyarzabal and Brais Mendez scored first-half goals to give Real Sociedad a comfortable 2-0 win at Salzburg in their Champions League Group D clash on Tuesday.
The Basque side dominated proceedings from the get-go and opened the scoring in the seventh minute when captain Oyarzabal slotted a left-footed strike from the edge of the box into the far corner.
Mendez extended their lead 20 minutes later beating the goalkeeper with a tidy finish after a quick counter-attack.
Oyarzabal missed a sitter two minutes later and Salzburg complained vociferously to the referee after they had a penalty award overturned following a lengthy VAR review early in the second half.
Real Sociedad are top of Group D on four points from two games, one ahead Salzburg in second.
