Sir Alex Ferguson has revealed one of his biggest regrets from Manchester United's victory over Chelsea in the 2008 Champions League final - not starting Park Ji-Sung.
The Red Devils emerged victorious in at a rain-soaked Luzhniki Stadium in Moscow, edging the Blues out on penalties after the game had finished 1-1 after extra time.
But Ferguson's decision to leave Park out of the starting line-up - he started both legs of the semi-final against Barcelona - was one that was questioned at the time, particularly as the South Korean had forged a reputation at Old Trafford for delivering in the 'big games'.
