It's baffles me. I'm not some football savant but I've watched Savio play for Girona and City and I saw a guy that's plays very well on the left, creative, incisive and scores a bit. I see this guy played on the right where he runs into blind alleys and the best aspects of his game are negated ie. his crossing and passing pick outs. All for the hope that he will beat a man cut in and shoot. Something that he's shown repeatedly to be very poor at.
Makes no sense to me other than him being used to cover for Kudus' injury. But then I see RDZ specifically say that he loves his wingers to cut in and shoot on goal so I wonder then maybe this is actually how he intends on using Savio long term. Waste of money if that is truly the intention.
I think the whole inverted wingers thing has got a bit silly, there's generally much more room to cut inside. Better to have them on their natural foot and if you have 2 of them they can swap wings now and again to mix it up.
It's fine if you're top tier like Messi, Salah etc but doesn't work for the average winger.
