What are you saying? That Messi can’t assist if he doesn’t have the ball? Well duh...
It's quite funny how somebody makes up an argument just for the sake of criticizing him and that suddenly becomes a narrative so many people agree on. Sounds like Messi would receive every pass beyond the half way line when in reality he's at ~60 passes per game, which is hardly much and in fact very close to de Bruyne, Neymar, Sancho etc. Don't hear anybody claiming that those guys only have so many assists because everything has to run through tgem.
