Younes Ibrahim marked his Brighton first-team debut with an assist seconds after coming on in a 4-0 Conference League victory.
The 18-year-old, who has Egyptian heritage, replaced Ibrahim Osman in the 67th minute with Brighton already three goals ahead.
He immediately crossed for Matt O’Riley to head home the fourth, registering his first goal contribution for the senior side within moments of entering the pitch.
Ibrahim had previously been an unused substitute in Brighton’s 5-0 Premier League win over Coventry City in September.
Georginio Rutter scored twice for Fabian Hürzeler’s side, with Jack Hinshelwood also on target as Brighton opened the league phase with three points.
Rutter broke the deadlock in the 41st minute after a VAR check confirmed that Osman had kept the ball in play during the build-up.
Hinshelwood doubled the lead in first-half stoppage time, before Rutter added his second after the break. O’Riley then completed the scoring from Ibrahim’s delivery.
Ibrahim arrived in the first team after scoring five goals and providing an assist in nine appearances for Brighton’s development sides this season.
The left-footed attacking midfielder, who can also play out wide, spent time in Luton Town and Chelsea’s youth systems before joining Brighton.
Egypt’s senior and youth national team staff are reportedly monitoring Ibrahim following his inclusion in Brighton’s Premier League squad.
The youngster has Egyptian parents and a Moroccan grandmother, alongside English and Australian citizenship.
Brighton next travel to Czech side Jablonec in the Conference League on October 22.
