The Independent dives into the lack of viable English managers and the system to train them:
The FA also suffers because the country’s main football competition is not really an English league but a global league that happens to be in England. Its ownership is international and their interest is in commercially growing clubs to international size, which means they just want the best coaches – no matter where they’re from. Hence its managerial make-up is four Spanish, three English, two Dutch, two Portuguese, one Australian, one Austrian, one Danish, one German, one Italian, one Northern Irish, one Scottish and one Welsh.
