They will all be converts of course, as there’s barely any such thing as a natural wing-back. One of the challenges for recruiting to this role is asking good enough wingers to come here and become wing-backs. I think wing-backs will almost certainly always be full backs by trade, and as such, will often struggle with the attacking talent required to be the primary wide threat, as opposed to the secondary one.
The pool of serviceable wing-backs is an extremely small one, and we need 4. I think Dorgu has just served to highlight the flaws in the role. I think he’d make a great left back. As a secondary wide threat, he just needs to overlap, occasionally kick and rush into space and get crosses in. As the primary one, he needs to go 1v1 himself and have a wider range of pass selection, which he is being exposed for (so far). I think the role is so important in this system, and there is enormous benefit of having a player here who can actually consistently do something with the ball, as they see a lot if it in attacking positions in space or isolated 1v1. I just don’t think asking a full back to provide the consistent quality needed here is realistic.
We can use wingers, and I guess even a second-rate winger (which is the best you will probably get for the role) would still have better ability and instincts than most full backs here. A top class winger, or a player who fancies himself to become one (Quenda), would not come and play wing-back. I think there’s a very small sweet-spot where you could probably get the perfect player. Someone above mentioned Dwight McNeil. He’s one I’ve mentioned on here for years as a player who I think could become a top left-back, but thinking of it - he’s probably even better suited to wing back. That said, I can’t see us buying another LWB after Dorgu and Leon in January. Anthony Elanga is another who I think would be just short of options at the very top level to play as a winger, so may be attracted by the opportunity to come back here as a RWB. He’s a vertical player, incredible athleticism and can run the right flank all day. I see him as similar to Alphonso Davies in profile.
