Dave Mackay vs Manchester United Watney Cup Final 1970

Dave Mackay's performance as sweeper for Derby County in their 4-1 win over Man Utd in the final of the inaugural Watney Cup. It's a short one with few defensive actions as it's edited from highlights rather than the full match, but it's interesting to hear the near-reverence with which the commentators speak about him, and his left peg certainly caused Utd problems from set pieces.
