During John Bostock's early teens it wasn't a case of choosing his GCSE options, but which of Europe's elite football clubs he fancied joining.
The teenager starlet was hailed as a generational talent when he came through the ranks at Crystal Palace, before making his first-team debut at 15. He couldn't even get changed with his Eagles team-mates on the night of his first appearance, such was his tender age.
Soon, the clamour for his signature led to what Palace chairman at the time Simon Jordan claimed to be a "litany of lies", with Tottenham winning the race for Bostock's signature. They paid less than £1m up front for the teenager, which Jordan said was the equivalent of "a packet of crisps".
