guys like billy davies and jim duffy have also spoke in the past about visiting clubs abroad to learn new training techniques and both admitted it was worlds apart from what went on in the uk.
it is no coincidence europeans are better footballers than those born and bred in the uk. ballwork is key. the reason we had so many good footballers in the olden days was because these lads grew up doing nothing but kicking a ball about streets all their days. time on the ball is all any player needs to improve his game. at rangers especially, our scouts and coaches are always looking for the biggest, the strongest and the fittest players as kids, not the best players.
