The 15-year-old, captain of England’s Under-15 side, has long been regarded as one of the standout prospects in English youth football.
Arsenal had actively pursued Allen for several weeks in an effort to integrate him into their academy.
However, Tottenham acted decisively to hijack the move, persuading Allen and his representatives with a compelling development pathway at Hotspur Way.
Securing Allen’s services represents a significant off-pitch victory for Tottenham over their arch-rivals. Having previously seen youth prospect Elijah Upson depart for Arsenal earlier in the window, Spurs were eager to respond in the academy recruitment market.
Allen’s arrival supports Tottenham’s ongoing effort to replenish their academy ranks after a series of departures.
With promising youngsters like Will Lankshear moving to Middlesbrough, Alfie Devine joining Preston North End, and Tynan Thompson heading to Manchester United, Spurs recognised the urgent need to recruit top-tier domestic talent to safeguard the club’s long-term future.
While Tottenham’s transfer window has featured several high-profile senior arrivals – including the marquee signings of Sandro Tonali, Mateus Fernandes, and Jan Paul van Hecke – the club’s hierarchy remain committed to maintaining a robust talent pipeline from academy level upwards.
Allen has been praised by scouts for his technical composure, tactical maturity, and exceptional leadership qualities in central midfield.
With final details agreed between Tottenham and West Ham, Allen is set to join Spurs’ academy ahead of the upcoming campaign.
