He definitely has played CB for us as I’ve seen it! He was used there much more frequently at U-18 level but he has played there for the U-23’s on occasions too, most notably in a back 3 with Turns & Tsoungui when we beat Liverpool 3-0 in December and in a back 4 against Northampton in the EFL Cup (Packham played at RB).
I do agree that he’s looked excellent at RB when played there, but that’s part of the reason I think he’s more suited to the current system than either Turns or Roberts are. Lamptey is on the bench to play RB/RWB, Offiah is there to play this weird attacking RCB role. IMO anyway, I could be miles off.
Fair enough, on the U18s particularly - I've never seen the U18s, for the obvious reason that they're not streamed. While not seeing all the U23s this season, I've watched them on stream whenever possible, and when they played down the road from me at FGR. Turns and Tsoungui were the CB pairing - and were working extremenly well together - with Offiah and Furlong (or Packham) at FB. This set up was scuppered when Tsoungui got his season ending injury, and the formation has flipped around a bit, with both Dendoncker and Roberts getting game time -with Offiah not always playing because of being on the bench for the 1st. team.
I've only seem him playing RB (or maybe, as you say RCB in some of the more unsettled line-ups since Tsoungui bowed out). Of course, young players don't always end up playing in the position they started in as yoofs. So is he a young CB who is now developing into a role as a RB/RWB? - he's certainly fast enough. Mind you, as a CB he's taller than Turns, Tsongui and Roberts too - so who knows
FWIW, I'm sticking with RB/RWB ........................... for now!
