Ismaila Sarr's opener was cancelled out by Enric Saborit, who was later sent off, but the Senegalese forward struck again in extra time to set up a last-eight clash with Serie A side Fiorentina.

After failing to score in its previous two matchups with Larnaca this season, Palace needed just 13 minutes to make the breakthrough as Sarr got on the end of a deflected pass from Adam Wharton and took the ball around the goalkeeper before scoring.

Maxence Lacroix missed a great chance to double Palace's lead on the stroke of half-time, heading straight at Zlatan Alomerovic from within the six-yard box, while Sarr fired twice off target after the break.

The second leg then saw two major twists shortly after the hour mark, with Saborit first powering a header into the bottom-left corner from Marcus Rohden's corner before receiving a second yellow card for fouling Sarr while the Palace winger was racing in behind.

Although Larnaca held on to take the match beyond normal time, Sarr swept home from Daichi Kamada's low cross in the 99th minute to seal victory for the Eagles. 

There were some unsavoury scenes towards the end of extra time when Larnaca's players thought they were awarded a penalty for a handball by Jean-Philippe Mateta before it was overturned by VAR, which led to fans throwing cups onto the pitch.

Things got worse for the host as Petros Ioannou was shown a straight red card for a poor challenge on Mateta, which came moments before Sarr struck the right post despite the goalkeeper leaving the goal unguarded as he went up the other end for a free-kick.
