There's the medieval version:
Stephen of MacClaren was taken to the Tower of London and beheaded...
And there's the modern version:
Steve McClaren was fired and given two and a half million pounds...
And as for the players, I think it should be compulsory for the next England manager to sign a document in which he or she affirms that he or she is aware of the fact that all the players available for the national team are complete and utter thickheads and that all tactics will be spelled out in tedious detail.
I have already made a start at writing the training manual.
Week 1: Passing the ball
Week 2: Passing the ball to another player
Week 3: Passing the ball to another player IN YOUR TEAM.
