When we were kids playing football on any waste bit of grass, playing until it was so dark that you couldn't see the ball anymore (you should try it nowadays kids, it's fun) we would all play the 'Pep' way. There were no centres after goals, you just restarted from behind the goal and played it through to who just happened to be up front at the time - anybody played in any position. You were called a goal hanger if you stayed up front too long and goodness forbid if you scored with a toe-bunger.
Then, when someone was deemed good enough we got a place in the school team and everything changed, the ball was treated like a ticking bomb to be got rid off at the first opportunity and lumped down the pitch. Therefore the bigger the player the more successful in this 'system'.
It didn't get better as you got older, unless you grew dramatically, same shite, skill was second to physique.
So.... it's going to take this generation of English footballers to mature into the 'Pep' style of manager before we see any difference in a system that was ingrained for over 50 years.
