Keane details Sunderland shortcomings

Roy Keane has claimed the arrival of American financier Ellis Short as Sunderland’s majority shareholder was a crucial factor in his decision to resign as manager of the club.

Keane quit in December after 27 months in charge at the Stadium of Light, insisting he had taken the Barclays Premier League strugglers – with whom he gained promotion from the Coca-Cola Championship in 2007 – as far as he could.
