The 15-year-old's request to terminate his Manchester United contract has caught the club off guard, coming just as United prepared to hand him his first-team debut this week. His social media activity has added intrigue to the situation, with Gabriel now following more Real Madrid players than Manchester United players, and with Real Madrid's academy the only youth setup he follows on the platform, alongside LaLiga's official account.
Despite his age, Gabriel already has close to a million followers across social media and holds a contract with Nike reported to be the most lucrative sponsorship deal ever signed by a teenager, surpassing the terms Neymar agreed at a similar age.
Some in England have compared the significance of a potential departure to Lionel Messi leaving La Masia as a boy, though it is worth noting Barcelona's own Lamine Yamal made his first-team debut at 15, showing precedent exists for clubs fast-tracking teenage talent into senior football.
Gabriel's recent form for United's youth sides lends weight to the hype. He scored a hat-trick in the Uefa Youth League in under 45 minutes in his most recent outing, performances that have prompted comparisons to Lionel Messi among English supporters, cementing his "Kid Messi" nickname. He was presented to United's academy on the same day as Cristiano Ronaldo Jr, another notable coincidence in a story already generating significant attention.
Where Gabriel ultimately ends up remains uncertain, with even those closest to the situation reportedly unclear on his next move. What does appear increasingly likely is that he will leave United in the near future, with a switch to another major European club regarded as the most probable outcome given the clubs already known to be interested in his signature.
Barcelona and Manchester City are also credited with interest in the teenager, while Bayern Munich are reported to be monitoring his situation as well. Manchester City had already made an approach to sign Gabriel last season, only for the move to be blocked, with the player remaining at Old Trafford at the time.
United are continuing to work to repair their relationship with Gabriel's camp, though his social media activity suggests his attention has already turned elsewhere.
