One of the most vicious derbies in football, a battle between Yorkshire and Lancashire, Leeds United and Manchester United have been rivals for a long time, and especially in the 1970s.
At one time, both teams were neck and neck at the top of the pile in England before Leeds' downfall in 1982, when they were relegated.
Despite the hostile attitude towards each other, both clubs have seen their share of players who have represented them both at some point in their careers.
