"I'm fed up with managers being made scapegoats for the state of our domestic game," he said in his column for The Sun. "The English working class is turning its back on football - and that is not my fault.
"I do have a lot of foreign players at Portsmouth but believe me I'd love nothing more than to field a team of 11 so-called 'home-grown' lads born within the city limits.

"Maybe they have the hunger and drive that working class boys of England had 30 years ago but now is replaced by video game passion," he said.
