Haissem Hassan registered his first European assist for Celtic, crossing for Camilo Durán to score against Benfica in the Europa League.
The Egypt winger came off the bench after the break and delivered from the right for Durán to head home in the 63rd minute.
The contribution was Hassan’s second assist since joining Celtic, coming in his 11th competitive appearance for the club.
Benfica had already built a three-goal half-time lead at Estádio da Luz. Jhon Durán converted a fifth-minute penalty and scored again in the 36th, either side of Alexander Bah’s 23rd-minute strike.
Hassan’s delivery briefly reduced the deficit to 3-1, before Vangelis Pavlidis added Benfica’s fourth in the 89th minute to seal the win.
Celtic had opened their league-phase campaign with a 3-1 home defeat to Ferencváros.
Haissem Hassan entered the Benfica match still waiting for his first Celtic goal after 10 competitive appearances.
His first Celtic assist came against St Johnstone on September 9. He beat his marker on the right and supplied Mika Baur for the 52nd-minute winner in a 1-0 victory.
Celtic signed Hassan from Oviedo on a four-year contract in August, with an option for another season.
They return to Scottish Premiership action against Hearts at Celtic Park on October 18.
