In the case of movement, out of all the stats you might want to pull up or want to me look at, that one is probably the most subjective because it's an intangible thing. Case in point, Lingard. His off the ball movement is absolutely better than Martial's.
You can't really measure things like, off the shoulder runs, seeing a pass 1-3 transitions before the play, channel runs, runs inside of defenders, outside of defenders, continued runs (making space for the player on the ball), sprints when standing up defenders, sprints when running alongside defenders with the ball or off etc etc...
Well actually you can but I'd be surprised to see if there's data out there for that, which is why I'm basing my opinion on watching games. If you can find me stats for those categories then sure I'd give you a critical analysis on something, which frankly everyone else is capable of i.e forming an observed opinion having watched 1000's of minutes.
I don't need to see received passes positional stats to know
generally Lingard's movement is superior. But that's not the point. I'm just simply saying, Martial can improve and we should expect better movement.
It's not an agenda or an outlandish claim.
It seems to me you're the one taking this personally.
