Whenever Manchester United are playing on their home ground of Old Trafford and the game is tied or United is losing, the referees will always allow enough extra time for Manchester United to tie or win the game.
In the September 20, 2009 Manchester Derby between Manchester United and Manchester City, there was supposed to be 4 minutes of extra time, already an inflated amount as there had been almost no injury stoppages. The match was tied at 3-3. The referees allowed over 6 minutes of extra time, a prime example of Old Trafford Time-keeping, giving United opportunity to score the winner.
