What do all these players have in common ?

• Beckenbauer
• Vogts
• Voller
• Klinsman

They are all great german players who went on to coach their national team. The best dutch players, too, seem to make an easy transition to coaching – Cruyff, Gullit, Rijkaard, van Basten.
How come english players don’t do the same ? It seems that you are not qualified to be an England manager until you have coached Swindon, Watford or Oxford.
