Sources: Barcelona plotting to sign Arsenal 14-yr-old who's being fast-tracked
The 14-year-old has recently trained with the Gunners' Under-18s and Under-21s teams, and they are looking to fast-track his development after he impressed club chiefs.
A tricky and exciting winger, he is seen as a hugely promising talent by his coaches at the Emirates, who believe he could be one for the future.
Jallow is also at the centre of an international tug-of-war between England and Spain, as their respective Under-15s sides have been battling to include him in their squads.
The two Spanish giants, Barcelona and Atletico Madrid, are believed to be keeping a close eye on his situation and could look to lure him away from Arsenal.
At just 14 years old, he remains a way off of being eligble for professional terms at Arsenal, but the club hope to show their faith after he stepped up the age groups.
Why do Arsenal want to keep hold of Bubacarr Jallow?
Former Man United chief scout Mick Brown told Football Insider over a year ago that Arsenal are placing emphasis on developing players through their academy.
Following the emergence of Bukayo Saka, Ethan Nwaneri, Myles Lewis-Skelly and Max Dowman, they are constantly eyeing the next generation of young talents.
Dowman represents and interesting comparison for Jallow, having made his first-team debut at just 15, and his fellow teenage prospect could look to follow in his footsteps.
Jallow has earned lofty comparisons to talents such as Neymar, and while his age must be factored in, coaches at the Emirates have liked what they have seen from him.
However, with interest from both Barcelona and Atletico Madrid lingering, they will have to make efforts to ensure the youngster remains part of their long-term plans.
Why do Arsenal have concerns about their academy?
Despite having facilitated the development of some of their current first-team stars, Arsenal have found it tricky to keep young talents and attract new signings at youth level.
Kyran Thompson became the latest exciting prospect to leave the Emirates this summer as he completed a move to Newcastle after turning down a contract offer from Arsenal.
Meanwhile, Football Insider reported in July that Arsenal are facing new concerns at academy level, after another young talent Mishel Nduka left to join Man City.
Nduka signed a scholarship contract with the Cityzens in August, with a professional contract expected to follow when he turns 17.
This follows previous academy exits, with the likes of Ayden Heaven and Chido Obi Martin having been lured to Man United in recent years, sparking concerns at the Emirates.
