Tottenham were forced to stop a loan move away for Troy Parrott on Friday's deadline day.
The Daily Mail says Parrott was blocked from leaving on loan due to an obscure UEFA rule that would have damaged the club's Champions League ambitions.
The 17-year-old was targeted by a host of clubs, primarily Burnley and Charlton, last month and both Spurs and Parrott saw the benefit of the forward leaving to play first-team football, particularly after Jose Mourinho admitted he felt the academy graduate was 'not ready' to step up to the first-team.
But a bizarre UEFA ruling in relation to homegrown players resulted in Spurs vetoing any loan move, effectively meaning he couldn't leave because of his birth date.
To qualify for UEFA's Champions League B list as a homegrown player, Parrott has to complete two continuous years at Tottenham.
But because he signed from Irish side Belvedere on his 16th birthday - February 4, 2018 - the two years required to be completed by Parrot will not conclude until he turns 18 on Tuesday.
