Ferguson wants Keane for another five years
The Irishman has recently returned to action after a troubled year which saw him walk out of Ireland's World Cup campaign, suffer a record fine and five-match ban after controversial comments in his autobiography and finally have to undergo a hip operation which kept him on the sidelines for four months.
During his absence, there had been suggestions that Keane's off-field problems outweighed his contribution on the field and also that his captaincy of the club could be under threat.
