Actually it was you who took the thread off course with your bizarre hatred of Dave Sexton a manager with an infinitely better record in the UK than Milne
Dave Sexton win rate at Coventry City = 31.25%
Gordon Milne win rate at Coventry City = 34.40%
Sexton's win rate at other clubs is hardly anything to write home about either, he's second bottom in a list of the last 10 Manchester United managers and he hardly fares well in a list of Chelsea managers either.
A significant portion of Gordon Milne's later managerial career was spent outside the UK so your comparison of their UK records is absurd. It is like me saying Milne's record in Turkey or Japan is way better than Sexton's. Funny how Sexton was never employed as a club manager again after leaving Coventry despite being just 53 when he left (remind me, how old was Fergie when he finally left Manchester United, or how old was Arsene Wenger when he left Arsenal, or Gordon Milne when he left Trabzonspor).
No hatred, Sexton was a poor manager for Coventry and did not fit well with a small club that has limited resources. A manager at Manchester United might have a squad large enough to be able to leave a player out because of personal animosity, but that doesn't work at a side like Coventry City. He also mismanaged the situation with the younger players when Garry Thompson departed, which led to several of them wanting to leave.
