Born in Oslo,[3] Bobb played for Lyn at youth level. In 2013, he began being linked with Portuguese club Porto, after performing well at a youth tournament in Algarve.[4] Porto reached out to Bobb's mother, Turid Gunnes [no], to convince the young footballer to sign with them, even going as far as to pay for the two of them to visit the club in Porto.[4] In October 2015, Gunnes moved to Portugal on her own, before signing documentation in November of the same year for Bobb to be enrolled in the Portuguese Football Federation.[4]
Despite the documentation being rejected by FIFA in January 2016, Bobb and his mother remained in Porto, and in January 2017 he attempted to sign with Escola de Futebol Hernâni Gonçalves.[4] However, FIFA were neither convinced that Bobb's mother had moved to Portugal of her own volition, to pursue an acting career, nor that the Escola de Futebol Hernâni Gonçalves were independent from Porto, and consequently refused Bobb an international transfer certificate.[4][5]
Bobb joined Premier League club Manchester City in July 2019.[6] In October of the same year, he was named by English newspaper The Guardian as the best young talent at Manchester City of his age group.[7]
After a relatively slow start, compared to other youth players brought in at the same time, Bobb cemented his place in Manchester City's under-23 side, notching a number of assists in his first full season.[8] As a reward for his fine form for the reserve side, Bobb was named on the Manchester City bench for the first time, in an FA Cup third round tie against Swindon Town on 7 January 2022, though he did not feature.[9][10]
On 2 September 2023, Bobb was given his Premier League debut against Fulham coming on as an 88th minute substitute for Phil Foden, where he was involved in the buildup leading to the 5th goal scored by fellow Norwegian Erling Haaland.[11] On 19 September, he made his Champions League debut against Red Star Belgrade, replacing Phil Foden in the 83rd minute in a 3–1 win.[12] On 13 December also against Red Star Belgrade, Bobb scored his first Champions League goal in a 3–2 victory.[13] On 13 January 2024, he scored his first Premier League goal in the 91st minute, securing a 3–2 comeback away win over Newcastle United.[14] A month later, on 26 February, he signed a new long-term contract at the club until 2029.[15]
International career
Born in Norway, Bobb is of partial Gambian and Norwegian descent.[16] Until 2023 he was a youth international for Norway, having played up to the Norway U21s.[17]
Bobb received his first call-up for the Norway men's team for the October 2023 international fixtures.[18] He made his senior debut as a 63rd minute substitute in the team's 4–0 UEFA Euro 2024 qualifying win over Cyprus on 12 October.[19]
On 16 November 2023, Bobb scored his first goal for Norway in a friendly match against the Faroe Islands.[20]
