In November 2021, he was scouted by Stabæk's Torgeir Bjarmann and Thomas Finstad in Nigeria during a showcase tournament.[1] He trained with Stabæk during the winter of 2021/2022 before returning after his visa expired.[2] Returning to Norway, he signed for Stabæk in late May 2022. The transfer from Nigerian club Bison was a loan with an option to buy.[3][4]
He scored his first goals in cup matches against semi-professional teams Notodden and Gjøvik-Lyn (twice).[5] After this he became a starting player for Stabæk. His goal against SK Brann was compared to Alanzinho's time at Stabæk.[6]VG also called him a "striker jewel".[7]
When Stabæk sold Oliver Valaker Edvardsen in July, the club announced they would spend the money on Orban's buyout option.[8] The contract tying Orban to Stabæk until the end of 2026 was announced on 3 August.[9] He became the top scorer in the 2022 Norwegian First Division with 16 goals, alongside Bård Finne.[10] Helping Stabæk win promotion to 2023 Eliteserien, Orban was also named Young Player of the Year in the First Division.[11][12]
On 31 January 2023, Orban joined Belgian Pro League side Gent on a permanent deal.[13] On 11 February, Orban scored two goals on his Pro League debut in a 3–3 draw with Westerlo.[14] On 12 March, Orban managed to score four goals in a 6–2 away win over Zulte Waregem, which made him the first Gent player to do so in the 21st century. All the goals came in the second-half.[15][16] In his very next game on 15 March, he scored a first-half hat-trick in 4–1 away win over İstanbul Başakşehir in the UEFA Europa Conference League round 16. The hat-trick was scored within three minutes and 25 seconds, setting a new record for the fastest hat-trick in UEFA club competitions, breaking the previous record of six minutes and 12 seconds held by Mohammed Salah in the Champions League.[17] In the 2023–24 Europa Conference League campaign of KAA Gent, Orban scored another European hat-trick, this time against Pogoń Szczecin in the first leg of the third qualification round, resulting in a 5–0 win for Gent.[18]
On 18 January 2024, Orban signed a four-and-a-half-year contract with Ligue 1 side Lyon, for a transfer fee of €12 million, which could rise to €20 million with add-ons, and a 20% sell-on clause.[19][20]
