His early promise saw him make his first-team debut at the age of 17 years and 19 days, breaking the record set by Lionel Messi.

In total, he spent four seasons at Camp Nou, scoring 41 goals in 162 games before he was sold in July 2011 to Italian side AS Roma for a fee of €12 million.

[5] A quick striker with quite notable dribbling skills, it was reported that he scored over 900 goals for various youth teams since joining the club as an eight-year-old, breaking Lionel Messi's record.

He also aided Barcelona to their first Copa del Rey win in 11 years by scoring five goals in the competition, including one in the final against Athletic Bilbao.

Bojan was an unused substitute in the 2009 UEFA Champions League Final against Manchester United, which Barcelona won 2–0 and saw them cap off a treble-winning campaign.

[17] On the first day of the 2009–10 La Liga campaign against Atlético Madrid, Bojan scored a header in the 18th minute courtesy of a flick-on from Seydou Keita.

[19] Coming off the bench as a late substitute for Andrés Iniesta, Bojan scored his first and only Champions League goal of the season against VfB Stuttgart.

[30] Following the 2012–13 season in Italy, Bojan returned to his former club Barcelona for €13 million,[31][32] having made 19 league appearances for Milan, and scoring three goals.

[34] Milan decided not to extend their loan of the young player, as they were not able to guarantee him minutes, while Roma did not exercise their option of additional €28 million to sign Bojan definitively.

[39] Director of football Marc Overmars and CEO Michael Kinsbergen flew into Barcelona a day prior to finalize the deal.

[40] Bojan explained that conversations with Johan Cruyff had influenced his decision to move to Ajax, as well as the opportunity to play in the Champions League.

[44] On 27 July 2013, Bojan won his first trophy with Ajax, winning the Johan Cruyff Shield (Dutch Super Cup) against AZ Alkmaar, 3–2 after extra time.

[45] He started the match on the right wing, playing for 61 minutes before being substituted off for Lucas Andersen, as Ajax acquired their eighth Dutch Super Cup title overall.

[50][51][52] Manager Mark Hughes said, "Anyone who knows European football will be aware of him as a player and the fact that he sees his future at Stoke City is really exciting.

[56] However, after a couple of ineffective performances, Hughes stated that he was prepared to give Bojan time to adapt to English football.

[61] On 26 December, he won a contested penalty in the first half at Goodison Park when referee Lee Mason declared that he had been fouled by Everton's James McCarthy; Bojan then converted the spot-kick past Tim Howard for the only goal of the game.

[67] A month later, he won a fourth-minute penalty when fouled by Swansea City's Ashley Williams, and dispatched it past Łukasz Fabiański for the only goal of the game at the Liberty Stadium.

[80] The situation came to a head in late December when Bojan was left out of the squad against Bolton Wanderers and supporters began chanting for his inclusion which angered Rowett.

[93] Bojan shot to prominence as a 15-year-old[94] at the UEFA European Under-17 Championship in Luxembourg in May 2006 when he was joint top-scorer, despite being a year younger than most of the other players in the tournament and only playing 40 minutes in four out of Spain's five matches.

There was controversy surrounding Bojan's call up to the Spain U17 squad for the 2007 FIFA U-17 World Cup in South Korea, because Barcelona wanted to keep him so that he could be part of their Asian tour.

Because of his performances, Bojan was given the Adidas Bronze Ball, naming him the third best player in the tournament, behind Nigeria's Macauley Chrisantus (silver) and Toni Kroos (gold).

[95] Bojan scored for the Spanish under-21s in their 2–0 win over Poland, on 12 October 2007, quickly establishing himself as an important player, also prompting rumours of an eventual call-up from senior side's manager Luis Aragonés.

[100] In an interview with The Guardian ten years later, he revealed that he missed both his international debut and UEFA Euro 2008 because of anxiety issues, covering it up by giving other reasons he could not play.

Bojan claims that his mental health issues were well known by members of the Spanish Football Federation, such as first team coach Luis Aragonés, sporting director Fernando Hierro and teammate Carles Puyol.

[101] He made his full Spanish debut on 10 September 2008 (at 18 years and 13 days) under Vicente del Bosque against Armenia, where he came on during the last ten minutes for Santi Cazorla and played on the right wing for his only senior cap.

[102] Bojan made his official debut with Catalonia in the friendly match against the Basque Country, on 29 December 2007 in Bilbao and he scored the Catalan goal in the 1–1 draw.

[103] On 13 September 2023, he became the football coordinator at his former club Barcelona, with his main task being monitoring the youngsters at La Masia, along with head of youth department, Alexanko.

[104] According to a genealogical research conducted by Diari Segre in 2011, Bojan is a fourth cousin of former teammate Lionel Messi; both are the great-great-great-grandchildren of Mariano Pérez Miralles and Teresa Llobrera Minguet, who married in El Poal in the catalan Comarca of Pla d'Urgell in 1846.
