The final was one of the Scot’s greatest nights in his 27-year tenure as Manchester United boss as his side edged a 6-5 win on penalties over Chelsea to secure the Europe’s top prize.
But despite winning the match, Ferguson feels bad for not selecting the South Korean, even though he started him in their semi-final second-leg victory over Barcelona.
“Well, to win the European Cup is fantastic,” Ferguson told MUTV. “It was a really great bunch of players with a great attitude about them and a good, strong squad.
“My problem in the 2008 final, maybe I even regret it to this day, was I left Ji-sung Park out completely in the final.

“He’d played such a great role and that’s the problem when you get to these finals.”
Ferguson went on to admit Dimitar Berbatov suffered similar harsh treatment when he was left out of the Champions League final squad that lost 3-1 to Barcelona in the final in 2011.
“At Wembley [against Barcelona two years later], I did it to Dimitar Berbatov and he took it badly. He didn’t deserve it,” he added.
“No player deserves to be left out of the final. That’s why we try hard at these European seminars with the coaches to try to get 11 subs in the final.
“You’ve got four or five sitting in the stand who made fantastic contributions in getting there.
“You start the tournament in September and go through to May and changes can happen. Maybe you sign a player in January, for instance, who can end up playing in the final.
“It’s a difficult part, always, picking a team for the final in Moscow and I had to make that horrible decision.”
