Not really.
He was dropped for the UCL final which we won.
Young must have some importance for Fergie to pick him, in fact I'd say the Park comparisons are quite valid.
The suggesdtion that we were chasing a second is laughable.That was the most toothless Arsenal side I've seen since Rioch's side came here.We had them comfortably held
This is true (the first bit), but he was then picked against Barcelona the second time around when he was in quality form during 10/11. He was preferred over Nani in spite of the fantastic season he'd had. Perhaps indispensable is too strong a term, but he was of much greater importance to us then than Young is now, and put in far, far better performances than the likes of that one today. Those performances against Chelsea and Arsenal were quality all-round performances, and not just for the defensive side of his game. More involved in the attack, and just ridiculously good in terms of work rate. In regards to the bolded bit, I'm not saying he doesn't have any importance, but Park was pretty much one of our players to be relied on in the big games. He put in great performances time and time again, even chipping in with goals on occasions. He was played a hell of a lot and performed very well more often than not.
As far as the last comment goes, I didn't mean that too literally (I don't mean we were going absolutely mental trying to get one). Nevertheless, it did look at times like Evra and Rooney were turning inside looking for other options despite him being open. I was surprised a more defensive option was deemed necessary today on the wing given that Arsenal really don't have anything too special on that side.
Despite all this like I say, Young is better than he's showing and will hopefully grow into the team more. I will admit that saying Park comparisons were way off the mark given similarities in role employed was a bit much also (although I believe the difference in performance and importance is actually quite large). Really though, I just don't quite 'get' him, and am not sure why I feel so strongly about it!
