Lisbon - A debut goal from new Serbian signing Filip Djuricic and another by captain Luisao gave Benfica a deserved 2-0 win over Anderlecht in Tuesday's Champions League Group C match at the Luz Stadium.
The Europa League runners-up went in front when forward Djuricic pounced on the rebound after keeper Silvio Proto could only parry a fourth-minute shot.
Benfica were in control throughout and Brazilian Luisao extended their lead with a neat volley after 30 minutes.
The Belgian visitors perked up after the break and were unlucky when they had a goal disallowed for offside.
Overall, though, Anderlecht struggled in attack and rarely penetrated Benfica's all-Serbian midfield wall of Nemanja Matic and Ljubomir Fejsa.
Benfica were content to settle for the two-goal victory margin in the second period as they claimed their first clean sheet of the season.
The Luz Stadium will stage this season's Champions League final.
In the other Group C match, Paris St Germain romped to a 4-1 win at Olympiakos Piraeus.
