Former England striker Dion Dublin believes questions should be asked over the lack of black and ethnic minority managers in the Barclays Premier League.

The Professional Footballers' Association wants tougher penalties for racist abuse including making it potentially a sackable offence, culprits ordered to attend awareness programmes and the introduction of the 'Rooney Rule' to boost the number of black coaches and managers.

The initiative proved a success in the United States, where it was brought in by the National Football League to make sure qualified black coaches are on interview lists for job vacancies.
