You know, driving at defenders isn't always the right choice. Messi for instance never does it. Sancho's brillant between the lines and there are very few players who can take multiple players out of the game through close control, body feints and intricate passing so effortlessly and consistently like Sancho. IMO that's worth much more than having a winger who can skin his full back through acceleration all the time. Sancho creates so much chaos in the opposition defense and thus space for his team mates. Compare that to someone like Coman who's among the best in the world in terms of one on ones and brillant in his own right but not close to being as impactful as Sancho is/can be when in form.
Plus he can definitely win one on ones as well. It's simply not such a frequent element of his game. I think he'll be incredible to dislike once he really found his spot in ETH'S tactical set up
