Fifteen-year-old Manchester United academy star JJ Gabriel has officially informed the club that he wants to cancel his registration and leave. United had planned to include the forward in their upcoming Carabao Cup match against Brighton, which would have made him the club's youngest-ever player. Despite this, the club remains hopeful of finding a way to resolve the situation and convince Gabriel to stay at Old Trafford. Gabriel, known for his exceptional talent, is attempting to become a free agent by formally notifying the club of his intent to cancel his registration. Manchester United believes the situation can be resolved and has not yet shown any indication of trying to persuade him to stay. However, the club is unsure of the reasons behind Gabriel's decision, especially since he was expected to play a key role in the Carabao Cup match. The club has not yet given up hope, as Gabriel still has a contract that runs through the end of the season. Gabriel, who was nicknamed "Kid Messi," made headlines last season as the youngest player to represent United in unofficial matches during pre-season. He also scored a hat-trick in United's Uefa Youth League victory over Sabah. Both head coach Michael Carrick and club legend Ryan Giggs have praised Gabriel, with Carrick calling him "a really big talent" and Giggs labeling him a "generational talent." Gabriel is one of the most promising talents to emerge from United's youth system in recent years. Last year, he won the Jimmy Murphy Young Player of the Year award and was named Under-18 Premier League Player of the Season. This season, he joined the club's Premier League 2 squad and scored impressive goals in his first two games. However, it is understood that Gabriel did not train with Carrick's squad at the end of last week, possibly due to some issues between the player's family and the club. The club is still trying to understand the reasons behind his decision, but they believe the situation can be resolved before the end of the season.
