JJ Gabriel, who won the Premier League Under-18 player of the year award last season, has been at odds with Manchester United over issues in the relationship between the player's family and the club. The 15-year-old striker did not train with Michael Carrick's squad at the end of last week, and it is understood that this has led to the current situation. BBC Football reports that Gabriel has a contract that runs to the end of the season, and the club have not yet given up hope of resolving the situation. United sources say they are unsure what has led to the situation developing the way it has.
