Ive thought about this recently myself, they all seem to go off the rails when they reach 26 or 27! They play well for a club, get a big money contract for a big club, win trophies, win player of the year awards, it all goes to their head, they start on the sniff, drinking, late night partying, 10 whores in a hotel room, yacht in Ibiza, cant be arsed with footy anymore and either turn into nobodies or turn to God!
MENTAL!
