Then you don't know too much about what you're talking about!
No, I know what I'm talking about. Having seen probably every game that Park played for us I'd say I'm in a pretty good position to have an opinion on him.
Ji Sung Park was an anti-footballer. He was deployed by Ferguson primarily when we needed to stifle opposition, similar to Phil Neville. He had a impressive work rate and good positioning. Other than that he added very little to the team. He was perfect for the role he played. Sat on the bench, waited quietly to be used and carried out instructions well. Technically he wasn't anything special. His passing range was limited. He scored few goals. Wasn't very good at crossing.
He play 154 games in the Premier League, scored 19 goals and had 21 assists. He had cross accuracy of 23% and a shooting accuracy of 33%. He had a tackle success of 71%. Says a it all really.

Jesse Lingard has obviously played a lot less since he's a lot younger, but he has already scored two match winning goals in two finals for us, effectively helping us win two trophies.
But in general his stats are very similar.
5 goals, 3 assists in 51 games. 38% shooting accuracy. 18% cross accuracy and a 75% tackle accuracy.
How Lingard is deployed is also similar to how Park was, but personally I think he offers a bit more going forwards than Park did.

edit;
I just want to add, the period that Park played for us, 2005 - 2012 was a very successful period for us. We reached the champions league final 3 times during that period.
Lets for arguments sakes say United played on average over those 7 seasons 70 games a season. Thats 490 games total. Park played 154 time for us (appearances, so probably includes off the bench appearances - its a wikipedia stat so someone might want to confirm that?).
That means he played 31.5% of the games we played between 2005 - 2012. Not a lot is it. If he were as good as you're trying to make out he was, as in a lot better than Lingard, you'd expect him to have played a lot more than that.
Thought it was worth adding.
