Raphinha, Yamal lead Barca into Champions League QFs

Benfica were level two minutes later from Nicolas Otamendi's header off a corner kick but Barca would have none of it. 

Teenage sensation Yamal restored the lead with a curling shot into the left corner, and Raphinha made it 3-1 on the night from another classy Barca attack in the 43rd, set up by Alejandro Balde.

Raphina had scored the goal in the last 16 first leg a week ago in Lisbon, and also twice in Barca's memorable 5-4 victory in their league stage duel at Benfica in January. 

In the quarter-finals, Barca will face last season's runners-up Borussia Dortmund or French club Lille. 

A minute of silence was observed before the kick-off for Barca team doctor Carles Minarro Garcia, who died on Saturday.
