The son of former Chelsea star Eidur Gudjohnsen lined up against the Blues on Thursday night with hopes of inflicting a defeat on his dad's old side.
Gudjohnsen made 263 appearances for the west London club during a glittering six-year spell. The versatile forward got his hands on two Premier League trophies and was a crucial member of Jose Mourinho's side that took the league by storm.
The Icelandic hero left the club in 2006 for Barcelona, where he lifted the Champions League and helped himself to a LaLiga title.
Eighteen years on, his son Andri Gudjohnsen lined up against Enzo Maresca's side in the Conference League at Stamford Bridge.
The 22-year-old, who was born in London, said in an interview with the BBC ahead of the game: 'I remember glimpses of those victories.

'The first thing I did was call my father. He already knew. It's special for me and for him. I was born when my father played there; it's kind of a unique draw.'
The striker has been in decent form this season, scoring twice from his eight appearances in the Belgium top flight.
Gudjohnsen signed with the side from Danish outfit Lyngby in the summer. He already has 26 caps at international lever for Iceland, scoring six goals. On Thursday night, the Belgian side were comfortably beaten by the Blues but Gudjohnsen was able to come away with an unforgettable moment.
The striker provided the assist for Tsuyoshi Watanabe's goal which halved Chelsea's lead.
Gent ended up losing their Conference League clash 4-2.
