I have nothing but ill-will towards Newcastle. I do believe that being black worked against him in addition to them being delusional about themselves.
The EPL is worse than the NFL when it comes to minorities in management. Secondly, minority managers are never given time to prove themselves. Ask John Barnes, Paul Ince and now Chris Houghton.
Think your reading too much into it tbh. I don't know Ashley but it has been obvious for a long time he didn't want Hughton, He also didn't want Alladyce. Pardew is something like the 9th manager is just over 5 years (not counting stand ins), its worse than even money Pardew will be the manager this time next year.
I think Barnes desrved the sack and Ince was in danger of relegation which most teams sack their manager. He wasn't handling it very well and got himself a bit pananoid, heard him since and seems to be much more sane about it.
I am sure I read somewhere that there aren't that many black/coloured (not sure what is PC anymore so sorry if I offended anybody) people taking coaching badges but could be wrong so don't quote me on it.
When it comes to replacing managers the top clubs tend to go foriegn, and the rest seem to just get on the same old merrygoround with the same old names switching seats.
The normal complaint is that young British managers (not white) don't get a chance, the truth is the clubs more likely to take a chance are also the clubs that can with a bad run get themselves into relegation trouble. I jsut don't think its a "colour / ethnic" problem, its a game problem imho.
