A decade ago this week, Sir Alex Ferguson made a decision over team selection he would later claim to be the toughest of his entire career.
The legendary Scot, who had made huge calls in the past at Manchester United in key games, involving Jim Leighton, Mark Hughes and Bryan Robson among others, and previously with Aberdeen and Scotland, agonised over his plans for the 2008 Champions League final against Chelsea.
Ji-sung Park was the most reliable of Ferguson's foot-soldiers and as selfless an individual you could wish to have in the team. The South Korean had started the memorable second leg of the semi-final against Barcelona and followed his instructions to the letter.
