Will is the same age as me and I played against him a few times, once at Deepdale in the Preston schools final thing they do every year. Nobody could get near him and even though his team were terrible we drew that final, and I remember thinking how above everyone else he was in terms of pace, strength and skill. We had a lad playing at Preston on our side too but Hayhurst stood out a mile.
Fast forward a few years to watching him play professional football and it was staggering how ineffective he looked, I know it sounds ridiculous/obvious because it is professional football, but it really makes you appreciate the level of the game, and all those people who say 'I could have made it blah blah blah' are usually talking out their arse.
