Ok so let me answer your question and then you answer to mine.
I think that there's a big problem in the coaching program in Britain, which is clearly shown by the fact that this once efficient manager's factory (Shankly, Busby, Clough, SAF, Paisley etc) hasn't produced 1 decent manager for a long long time. I also believe that unless there's an exceptional case (ex the one faced by Barcelona during Pep) a manager should have sound managerial experience to manage a top club.
Now please answer my questions
Since when the British people are a race?
Can you list a number of British managers (who aren't dead or retired) who were successful in football? Really successful I mean, (CL, league titles in top leagues etc)
Dev, you've clearly got a down on British managers but to be fair, the only criticisms you can level at them is that they tend to only speak English so managing in other leagues is really a non starter for most with rare exceptions like Bobby Robson. It's therefore not likely that you'll produce a list of hugely successful British managers apart from Fergie due to the dominance of United under Fergie, Arsenal under Wenger and the foreign legions at Chelsea, City and Liverpool Exclude those however and you'll find that a significant majority of the other managers who have come close in the Premier League (say qualified for Europe) have been British 43 out of 53.
Dalglish who won it with Blackburn, Keegan, Mike Walker, Ron Atkinson, Frank Clark, Roy Evans, Howard Wilkinson, Brian Little, George Graham, Roy Hodgson, David O Leary, Bobby Robson, Souness, Strachan, Alardyce, Steve Mclaren, Moyes, Hughes, Martin O Neill, Redknapp, Pardew, Sherwood & Rodgers. Maybe non of them quite sit at the top table in terms of global football management but there's at least half a dozen very good managers in there who unfortunately for them happened to be managing in the toughest league in world football at a time when you had 2 or 3 teams who dominated the league.
With the exceptions of Mourinho and Wenger, how many other foreign managers have come in and really set the premiership alight?
