Barcelona staged an astonishing comeback at Estádio da Luz, overturning a 4-2 deficit to defeat Benfica 5-4 in a dramatic UEFA Champions League encounter.

Benfica struck early when Fredrik Aursnes set up Vangelis Pavlidis for a close-range opener.

Barcelona levelled soon after as Robert Lewandowski converted a penalty following Tomás Araújo's foul on Alejandro Balde.

However, Pavlidis restored Benfica's lead after capitalizing on a defensive error, before completing his hat-trick from the penalty spot after Wojciech Szczęsny fouled Kerem Aktürkoğlu.
