Early career and move to Portugal Born in
Oslo, Bobb played for
Lyn at youth level. In 2013, he began being linked with Portuguese club
Porto at the age of 10, after performing well at a youth tournament in
Algarve. Porto reached out to Bobb's mother, , 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. The case reached the
Court of Arbitration for Sport, who sided with FIFA, and Bobb was told to return to
Norway. 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. 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. 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. 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. 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. On 13 December also against Red Star Belgrade, Bobb scored his first Champions League goal in a 3–2 victory. 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, after a
Kevin De Bruyne cross. A month later, on 26 February, he signed a new long-term contract at the club until 2029. In August 2024, during pre-season training with Manchester City, Bobb suffered a fractured leg that required surgery. The injury was initially expected to sideline him for up to four months. However, manager Pep Guardiola later confirmed that while the fracture had healed, Bobb was not yet ready to return to matches and was only taking part in partial team training by January 2025. In late April 2025, Bobb suffered a hamstring injury in training, forcing him to miss the FA Cup semi-final and several matches late in the season. He returned to team training at the end of the season and rejoined the squad for the
2025 FIFA Club World Cup. On 22 June, he scored his first goal since his return from injury in City's 6–0 group stage win against
Al Ain after coming on as a substitute.
Fulham Bobb joined
Premier League club
Fulham in January 2026, agreeing a five-and-a-half-year deal for £27m. ==International career==
