I have to say, the first thing I noticed in the United trailer was that on one of the Beckham goals (the free kick), the diving keeper seems to hit an invisible wall when getting close to his right post.
It looks really weird, it's as if he was going to save it but he wasn't allowed to because it's Beckham (and I truly think that's how PES works). But it might just be me. Take a look and tell me if you see it.
(That's after going "huh, that's the exact same animation from the E3 trailer but reskinned as a Man United player" a couple of times - which always makes me laugh, you can't brag about player individuality and then show multiple different players doing the exact same thing in the exact same position using the exact same animations. Just take an extra day to record/animate a slightly different scenario.)
EDIT: Turns out I'm not going mad. Check out 2mins exactly in the United trailer, but change your YouTube play speed to the slowest possible... (Click the settings cog, then go to "playback speed".)
I dont know man. Its a cutscene to show the skills Beckham had in the old days. Of course hes gonna score lol. If the trailer focused on Kahn for example, they would probably show a sick save from him..
